Somebody knows about this matter because if you use my Ether wallet and you can see some time you get fake coin. If you follow token contact address and you can see all the digit or 0 and 0 it is a fake coin. In this online industry there is lots of token scam. If you want to see scam list so you can search in Google and you can get lots of scam coin. There are lots of people buy scam coin, after all they lost his money in cryptocurrency market.
On the occasion you talk about this, I also give my opinion. The current token ERC20 has many tokens that are coincident with each other, and is causing investors a headache because of this. They may mistakenly move to an exchange whose tokens are unsupported because of repeated token names.
