I think you make a confusion between crypto and blockchain. I would rather say that blockchain is the future, not crypto in general, because blockchain as technology is just great and many institutions already implemented it.
However, they can use blockchain without crypto as it happens today.
It is possible, and blockchain appeared before the first crypto, but there is no need now to use blockchain without cryptocurrency as it is too complicated. The role of cryptocurrency in this scheme comes down to the question of who decides which blocks will be added to the blockchain. Bitcoin is decentralized, and no one has the power to make this decision alone. It remains safe and the most secure choice.
Many people periodically share their opinions about the blockchain technology and Bitcoin on social media. They have similar tweets which share the idea of "blockchain is the reason why they are in the crypto space, not the Bitcoin" but their approach is wrong in my opinion. Blockchain technology can be used as an efficient solution to the real-world problems due to the transparency.
All the complaints by the traders are the consequence of the poor trading results by the inexperienced traders. If there are 5 successful traders who are able to trade in bear-bull-flat market conditions, they don't have time for complaining on the public forums in my opinion. The experienced traders check their portfolio and look for the slowly moving altcoins which can be easily replaced. Other traders don't even think about it and they cry like a teenager. Becoming a professional trader takes years if you are not willing to accept these risks, go to find the reliable source of making money. No offense, but it is annoying to see the same opinion.
