It was supposed to surpass ico and be a better crowdfunding method; but it has gone cold faster than ico did.
If you compare Your experiences too; between altcoin and bitcoin; you would notice that
1. Altcoins are so many; that they replace one another.
If an old altcoin dies
New altcoins will replace them and old one will be forgotten... It goes on and on
2. Bitcoin has maintained its class and importance;
Is it that bitcoin is the only hope for the future ??
With Bitcoin dominance increasing it really is the future of Cryptocurrency, gone are the old days when new coins will have full support and investors in a hurry to invest in a new coin thinking it's the next best thing, that's not going to happen now, investors are more wiser than, they knew some new coins are just recycled of the old one with nothing to offer.
Bitcoin should be our main portfolio because of it's growing dominance, with so many scams ICO in the past, investors want to regain their losses by investing in a more stable coin like Bitcoin, Ethereum Eos among others, I can't keep with the number of coins that has gone from a hype to dump coins.
Yes bitcoin is one of my investments in the future because it tends to be stable compared to altcoin, several times I have asked the future of bitcoin experts say 2022 is the key of bitcoin because many big changes will rely on cryptocurrency assets.
