The cost of checking an address is lower than analogues - $0.20, repeated checks of a previously checked address are free.
So, BESTCHANGE now accepts deposits directly from users.

I tried this service. It is true that the fee is $0.2, but when you choose a crypto address, you must pay $0.2 in that cryptocurrency. If I want to check
* my Bitcoin address, I must pay in Bitcoin. The lowest fee is ~10 sat/vB. Which means that the transaction fees are higher than the service costs.
Suggestions:
- Option to pay from the referral balance.
- Payment only via Lightning Network or cryptocurrencies that have transaction fees less than $0.2.
* Personally, I don't like AML analyzer concept
If we understand correctly, you are referring to making a payment using the same crypto asset whose address you plan to verify.
Our website currently provides a range of payment options, including two cryptocurrency methods. We've specifically chosen Bitcoin Lightning and Tron (TRX) due to their low or non-existent fees, which can save you money on transactions.
For instance, if your Tron (TRX) address has sufficient "Bandwidth" and "Energy," the transaction will be completed without any commission costs, considering a fee of $0.20.
Regarding your suggestions:
Option to pay from the referral balance: Our team will consider this proposal in future iterations of our service. We are keen on creating a convenient and accessible tool for our users.
Payment only via Lightning Network or cryptocurrencies with transaction fees less than $0.2: Reducing the available payment options for checks is not our priority. On the contrary, our goal is to expand payment methods for our clients' convenience gradually.
