Well they say Bitcoin and crypto is the future. My biggest fear is a new innovation will come out that bypass all hindrances to financial transparency and decentralization. We dont know yet what is there to come so if ever theres a new tech that introduced that surpasses the ability of bitcoin and other and lead to migration to this new one which I believe not present yet (Hope not yet).
One thing that worries our investors and many investors is the volatility of Bitcoin or other cryptocurrencies, the adoption of which can lead to a sudden drop in volatility.
We see that inflation is a major concern and money is being printed and changed due to changes in the economy of different countries due to pandemics etc. This situation is why Bitcoin is hedging against inflation (considering CPI) and why gold is not a good investment.
segwit2x They are implement Bitcoin and take it to scale but ultimately develop it with negligible scalability, which has annoyed many Bitcoin investors and some have lost faith in it. Their main problem is the lack of strong leaders!
I think if a strong leader comes and starts working on this......that would be great.
