This year; ieo unfolded.
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 ??
In fact, bitcoin's growth is only due to its market pumping prices. In terms of technology, bitcoin currently does not rank in the top 14 of CMC. In terms of transaction speed, it is outside the top 50 in CMC. In terms of fees, it ranks the top 1 of the most expensive transaction fees.
In general, bitcoin is not bringing any good value to the market and humanity, it is only living on the money of the whales. I believe that one day, when humanity more emphasis on technology, Bitcoin will be death.
