I'm not so sure about the various industries that are often quoted as being suitable for blockchain applications. I don't think all of them will benefit from the blockchain. You don't always need decentralized consensus. But I'm sure that they crypto-market cap will eventually reach the range of tens of trillions of dollars.
I believe the growth of the crypto market is inevitable. More and more investors are realizing the potential of bitcoin as perfect money. There are speculations that bitcoin may become a
fractional reserve currency for the national states in one of the future waves of adoption.
As far as the alts are concerned, it's hard to tell. The question is how many of today's altcoins are still going to be alive in 15 years? Maybe 10 to 15 percent tops. There is simply no room for all of them.
Right, the growth is certainly inevitable and there is nothing that would be stopping it. Blockchain technology is certainly here to stay and it is apparently the future and this is one technology everyone is already trying to be a part of, it may not affect every sector primarily.
But we both know it would affect a huge number of sectors in the long run and this simply shows that the more the sectors that this technology keeps penetrating, the more the growth of the cryptocurrency space. Therefore, experiencing a huge market capitalization in some years to come will not be surprising to me at all.
Also, as we keep seeing blockchain technology being implemented in various sectors, companies, organizations and the likes, the more we will get to see the space growing hugely and having a market cap as much as that would not be surprising at all. We are still new and here we are with the current market cap, imagine in few years to come what it would be like.
