Ethereum platform gained popularity because it was the first one that allowed to hold bounty, so many projects took advantage of this advantage
Yes, but today the ETH platform does not look as attractive as before.
Of course, today Ethereum does not look as revolutionary as it was a few years ago. I agree that there are many solutions from competitors and some of them really deserve attention. But it seems to me that Ethereum will still be in indisputable leaders for a long time.
There are competitors for ethereum, but they are unlikely to win this race. Ethereum is the basis of almost all projects and it will be very difficult to eradicate it from the top 3.
