I didn't click the link but I've got questions.
Why there's a need to connect our wallets? most of the trackers are settable. You just need to input the number of coins you hold, add/remove.
Precisely to avoid having to add coins one by one. I have been a holder for years and I find wallets with more than 70 different currencies and many times some of my currencies are not listed. With our website, all the coins are listed. Also, if you have several wallets, you can manage them independently. And now, you can put wallets ERC20 or NEO. Our website supports 100% of the tokens.
