# How to choose the length of Tron Energy rental? Why is renting for one day the most cost-effective a

Many people gradually realize the importance of leasing Tron energy before transferring USDT to effectively reduce the USDT transfer fees. But when faced with various leasing durations, how should you choose? There are options for 1 hour, 1 day, 2 days, 3 days, one week, half a month, one month, and even those claiming unlimited duration. If you want to save on transaction fees, please continue reading.

First, let's talk about 1 hour. The price for 1 hour is cheaper. On platforms like mefree.net, leasing 32,000 energy for 1 hour costs only 3 TRX. This is suitable for those who seek low prices and anticipate a high volume of USDT transactions within 1 hour. For example, Mr. Wang anticipates conducting 10 USDT transfers in the next hour, so he can transfer 30 TRX to mefree.net and receive 320,000 energy. The advantage of leasing for 1 hour is that it has a low price and is flexible. The downside is that it's a short time and may not be suitable for leasing a large amount at once; you can only rent based on your immediate needs, which can be inconvenient for users.

Now, let's talk about the energy duration of 1 day. I can tell you that leasing for 1 day is the most cost-effective option. Buckle up, we're going for a high-speed ride, and if necessary, you can grab a piece of paper and a pen to calculate. On mefree.net, the price for leasing for 1 day is 5 TRX. "1 day" means that the energy is valid for 24 hours from the moment of distribution. Why is 1 day the most cost-effective? It's because of the Tron mechanism. If observant Tron users pay attention to energy changes, they'll notice that the energy value starts to increase every second after it's used up. That's because the Tron mechanism restores energy to full within 24 hours after it's depleted. Still not getting it?

Let's say, for example, on September 6th at 11:30 AM, you leased 32,000 energy for 1 day. Then, at 11:31 AM, you used 32,000 energy for a USDT transfer. According to the Tron mechanism, the energy starts to replenish immediately and will be fully restored within 24 hours. In other words, at 11:31 AM on September 7th, your energy will be back to 32,000. You might wonder, "Why is this relevant when my energy expired at 11:30 AM, and you've already taken it back? What use is there in having 32,000 energy restored?" But what if you used it before we reclaimed it? Let's do a math problem: There are 24 hours in a day, which means there are 48 half-hours. So, let's calculate how much energy you'll have restored 30 minutes before the reclamation of energy. 32,000 ÷ 48 × (48-1) ≈ 31,333 energy. So, even if you used energy 30 minutes before the reclamation, you would still have approximately 31,333 energy to use. Currently, the energy required for 1 USDT transfer is 31,895 energy, so you would only be short by 562 energy, which is not much even if you consider it as Tron burned as a fee, roughly 0.2 TRX. In other words, when you lease 1 day of energy, you can effectively use it for 2 transactions.

Remember, energy starts to recover only after it's used up. Leasing energy for 1 hour is essentially the same as recovering energy and leasing it to the next user after 24 hours when it's full again. If you understood the above, you can further understand the following examples.

Example 1:

On September 6th at 11:30 AM, I leased 20 units of energy for 1 day, which means I leased 640,000 energy with a validity of 24 hours. Since I was busy, I used all 20 units by 11:40 AM. So, starting from 11:40 AM, the energy replenishes every hour by 640,000 ÷ 24 ≈ 26,667 energy. Based on this recovery rate, it means that every 2 hours, you can at least perform an additional transaction. Calculating at 1.5 transactions per 2 hours, before the energy expires, you can effectively perform an additional 1.5 × 12 = 18 transactions. This means that by leasing 20 units, you can perform 38 transactions within 24 hours.

Example 2:

On September 6th at 11:30 AM, I leased 20 units of energy for 1 day, which means I leased 640,000 energy with a validity of 24 hours. At 12:30 PM, I used 10 units of energy, which means, starting from 12 PM, it replenishes 320,000 (the value of 10 units) ÷ 24 ≈ 13,333 energy every hour, which translates to 1 extra transaction energy every 3 hours. At 6:30 PM, I used the remaining 10 units of energy. So, after 6:30 PM, the energy replenishes at a rate of 13,333 (from the previous 10 units) + 13,333 (the replenishment rate after 18:30) ≈ 26,666 energy per hour. This means, before energy is reclaimed, you can perform roughly 17 transactions [(from 18:30 to the next day at 11:30) ÷ 2 × 1.5 (as explained in example 1) + 2 transactions (from 12:30 to 18:30, 6 hours, 1 extra transaction every 3 hours)]. So, leasing 20 units allows you to perform 34-35 transactions within 24 hours.

The above two examples illustrate that energy starts recovering after it's used up, and the data is rounded to facilitate calculations and understanding based on time and transactions.

What about 3 days, 5 days, 7 days, and one month? Let's take the example of buying energy for 3 days. In reality, you're given 32,000 energy but with a 3-day lockup, and after 3 days, it's reclaimed. For instance, if you leased 32,000 energy for 3 days at 11:30 AM and used it at 11:32 AM, you'd have to wait until 11:32 AM the next day to have 32,000 energy available again. If you're leasing day by day, the same 32,000 energy would be available the next day at 11:00 AM. So, if you needed to transfer USDT, you could do so right away. When it expires at 11:30 AM, you would have already used it for two transactions. Then, if you need to transfer USDT again, you can lease 32,000 energy for 1 day. This means that with 32,000 energy, you can effectively perform 4 transactions in 2 days.

So, what about those claiming unlimited duration energy? Well, if you've read my previous articles, you'd know that unlimited duration energy is actually a gimmick. Any energy leasing platform with a leasing duration immediately provides you with energy proportional to what you've leased. Unlimited duration energy, on the other hand, requires you to make an upfront deposit. For instance, if you buy 100 units, they might lock up 64,000 energy in your address, which is equivalent to the cost of 2 transactions. They then monitor your USDT transfers. For example, if you make 1 transfer, they'll immediately add 1 unit of energy to your address, rather than providing you with the full energy you need.

This article is indeed a bit complex, and if you understand it, great; if not, just consider it as rambling. Additionally, each transaction here is based on 32,000 energy as a standard. If the recipient of the USDT transfer doesn't have USDT, it will consume 64,895 energy, which is equivalent to the energy cost of 2 transactions.
