~snip~. Can you imagine ETH only came 5 years later? And Defi coins are barely 1 or 2 years old now? Smart contract chains? All a handful of years!
We do need this space to mature and while it does, it's gonna be full of risk. But that's expected:)
It's true what you said, blockchain will grow very fast. People will make improvements to existing technology. So it will not last forever, some will die and some will live. The market will develop so fast we have to be able to read the opportunity to make a profit. I think this industry will continue to advance this will be a revolution. Now refuse someday it will surely be accepted. So this is an opportunity to make life better and or make it worse it depends on your strength to survive and learn new things.
