certainly prefer crypto, I’m tired with the bank operation. Crypto would be the future for investment.

I don’t think blockchain could be fully replaced by bank as bank is financial institutions that play a key role in the economy. On the other hand, blockchain is just a technology for a growing list of data. 

In my opinion, bitcoin is more worth to buy. First of all, It has a more steady market than the altcoin. Although, it is much expensive than the altcoin, I would say bitcoin gives more confidence to the investors.

I agree that bitcoin or other kind of cryptocurrency should be regulated. Regulation doesn't mean that we have to give up our freedom, but instead, rules protect us from scam stuff like that. 

I think the main issue of altcoin is that they are usually less circulated in the cryptocurrency market. Comparing the altcoin like ETH, bitcoin is more usable and tradable in the market.
