As we all remember from 2018, many fundamental projects with technologically strong ambitions simply did not survive it.
What projects do you mean? Give the examples, please.
Anyway, are you sure those projects that didn't survive have strong fundamentals?
I think the dead projects were only projects that have weak fundamentals. Note that strong ambition doesn't mean having a strong fundamental!
Over the past 2 years, a lot of cool blockchains have appeared with their ecosystems, such as Dot, Near, Solana, Matic, AVAX etc.
do you think their technological potential will be able to survive the next trend?
The coins/tokens you stated above, I am sure that they have a strong fundamental.
They surely have a big chance to survive a long time. Their technology will be always improved since they have good teams.
