Then buy these 100BTC at these idiotic and low prices such as $1000-$1200 and forget about crypto after storing them in unused addresses and printing a few paper wallets as back up then go live your life for another 10-15 years and when price reached your goal sell them to have $50M in cash at your disposal, imagine someone with 500K bitcoins could be a billionaire.
If the funds permit, then why not do so. Just do not need all the money to invest in bitcoin in order not to remain at a loss, because no one can accurately predict what awaits us.
Only if you have cash to burn, can you contemplate doing something like this. If Bitcoin is replaced by ETH or some other alt, then the half million dollar price prediction will look very silly. It could pay off, but it is very, very risky.
ETH can't never replace BTC, because Ethereum and Bitcoin are very different things. ETH is known for "proof of vitalik", it will NEVER be the unit of account of crypto, it will never be the gold of crypto, BTC will remain #1.
I dont agree with you, you cannot just say that bitcoin is something unbeatable, and a cryptocurrency that will always have the biggest part of the market, because it may change any time soon.
It is all about some incident, that will make investors lose trust in bitcoin, or just the incident that will make some altcoin insanely strong on market.
Obviously, such a event may never happen, and bitcoin can always stay number one currency, but as everybody already know, humanity invents new technologies very fast, and why cannot that just happen in the cryptocurrencies world? It is about creation of new, great altcoin that is going to be backed up by a strong technology, even better than blockchain and bitcoin infrastructure.
I dont believe in bitcoin going up to half a million dollars, but i also do not expect it to die. I think it will be somewhere around 3000-4000$ level during 2030, but that is only my perspective.
