TRON crypto currently is in 10th place with total market value - 7.6$ billions - https://coinmarketcap.com/
yea but there is no trustworthy stablecoin build on NANO, so to transfer value without fee I have to be exposed to currency risk on super volatile asset. So its not worth it.
As for Tron, the transfer on it is free only if you keep a large amount of money blocked in your stake for a week, which exposes it to currency risk, which is, in my opinion, not worth several free transactions a day. Especially since bitcoin transfers currently cost less than $1. But despite this, I believe that TRX is one of maybe 10-20 projects worth spending some time to do detailed research. The remaining 19,980 projects listed on CMC are poor copies or attempts to extort money through hidden pyramid schemes
And average Bitcoin transfers currently do not cost less than 1$, but much more.
