This token you are referring to?
https://coinmarketcap.com/currencies/zebec-network/According to Coinmarketcap data this token is not on Coinbase.
I would not invest anything for now in any altcoin that has a low marketcap, considering that now that bitcoin is starting to crash, the price of altcoins like this token will experience a severe decline.
To invest in altcoins the risk is too high --- and the recovery to increase the price is usually difficult again.
Yes that is the one, it is only a 250m market cap so should go down quite a bit if Bitcoin continues to fall next few months but when good times return it will 5-10x in no time as many low cap altcoins do.
I will keep an eye on it, won’t buy yet as we are going down currently.
