This is a question that has been on the minds of many people since Bloktopia was first announced. The simple answer is: no, you cannot buy Bloktopia on Coinbase.
The reason for this is that Bloktopia is not yet listed on any major exchanges, and Coinbase does not list any assets that are not listed on a major exchange.
However, this does not mean that you cannot buy Bloktopia in the future. Once Bloktopia is listed on a major exchange, it is highly likely that Coinbase will list it as well.
So if you’re patient, you may be able to buy Bloktopia on Coinbase in the future.
