I think that this will hinder widespread adoption. What do all of you think?
Whales, in my opinion, are not the primary deterrent to widespread adoption of bitcoin. I believe that cash is much more user-friendly and practical than bitcoin. Alternatively, once the cash is gone, cryptocurrencies like bitcoin (possibly privacy coins) will take its place.
Cash through its years and years of history have secured the position to be the user-friendly one and getting used even when more and more alternate gateways have got opened in the form of digital payments and cryptocurrencies. Cash to get out of usage is not gonna happen at the shortest or in the future.
