There are some tokens in my ethereum wallet that have lost value to the extent I don't think they can ever recover even if the bull market starts tomorrow due to the level of competition in the altcoin market. I also bought some coins but can't remember the password or name of exchange i bought them on (thinking it was cryptopia) I didn't bother transferring it off the exchange and most of them were bought around 1satoshi.
Back to my ethereum wallet, each time I see those worthless token I just laugh and continue with what I login my wallet to do. If you ask me why I'm still holding does tokens in my wallet I can't give a reply. Why are you still holding those shitcoins sorry altcoin
If these tokens bother you, send them to the zero address of Ethereum. They are on the wallet and do not ask you to feed them. You do not spend money on their maintenance. Let them lay. Suddenly one of them will someday grow in value and you will be able to earn very well on this token.
