So I did some research and got the basic picture about ICO, that is when an ICO starts, during its Pre-Token sale, it offers its tokens which we buy by sending the cyptocurrency that it supports to the crowdsale address. Then we get to store those tokens in a bitcoin wallet that supports the ETH-20 protocol, which is kind of the standard protocol nowadays.
What I do not understand, however, is what do we do once those new tokens that we got have a higher value? How do we sell them for BTC or any other kind of online currency, or maybe use those tokens?
what you do not understand is where to sell it right ?
just tell me where is the place that you said it has a higher value than before ?
you can tell me like that which mean that token already tradeable in every exchanger or some exchangers.
so just sell it in there,
but if it's based on Waves you can sell it directly on wavesdex.
other than waves,usually it's tradable on exchangers like Bittrex,Nova,C-Cex and even you can find it on Kraken,
for example Escudo if i remember it correctly,but it get delisted yesterday.
