Your balance checker is much faster than EasyBalance. I checked 25-30 addresses from the list LoyceV posted and the speed of EasyBalance isn't comparable.
I also notice that EasyBalance made mistakes when calculating the balance of certain addresses. This one for exampe > 1BtCdfQB8q4H8dwTECg2nwbvimUEvFFwqn
EasyBalance shows only 0.00000547 BTC
Your checker has the correct balance of 50.00000547 BTC
Any idea why that happens? And have you noticed similar behavior from your checker?
yes. EasyBalance is a great website. His tool also checks for balances in other blockchains/coins.
He used a bigger setTimeout than I did (he is more worried about IP blocks, probably). This is why searches from there takes too long.
That being said, I had a lot of troubles using this easybalance (this is why I created mine)
I also had problems with balances and bugs using his website. I cannot search for more than 5 addresses there (it freezes), and I can't search for native segwit addresses there as well.
He also go through all dozens of explorers api checking for balances. I don't know why he does that, mybe they are backups in case one of them goes down. Whichi is a lot worse for privacy.
So his tools is not useful to me, as I have many native segwit and I need to search for many addresses. You can check hundreds of address without any problem in my tool .
