Adoption is essential in my opinion, at the very least within the sphere that it operates, otherwise how can it be used as a viable currency? Looking back at the origins of crypto, their vision was about decentralization and not exclusivity. The risk will always be there that the big institutions (or even big individuals) come in and end up controlling a majority share, basically defeating the objective, but without adoption currency is basically useless. I'm looking forward to more decentralized exchanges taking a bigger share of the market, the current system is too heavily biased towards the main exchanges, but that's another conversation altogether.
