BONUSBTC is a scam token sent to peoples wallets to trick them into trying to login to a fake counterwallet instance using their 12-word passphrase... at that point the scammers have the 12-word passphrase for the persons wallet and then steal the funds/assets in the wallet

I have updated xchain.io to no longer display the BONUSBTC asset description which contained the URL to the fake counterwallet login.... This should hopefully stop some ppl from losing funds to these scammers.

Same scam with COUNTEREVENT asset was pulled years ago as well.
