You argument is totally wrong about Tron. Every coin has pros and cons,& Ethereum aren't all round perfect.
I agree, maybe OP lost a lot of money on Tron. But if we compare Tron and Ethereum, Ethereum is far better!
Another thing most smart contracts layers these days are most likely copy-paste from Ethereum. That's why Ethereum is most used up to now even though there is a lot of new networks.
Another thing is if you take a look at Tron Defi TVL.
