The most expensive transaction right now is for every coin that has its parent Smartcontracts, Ethereum is still Ethereum, which reaches 30-50 USD for the token delivery. Oh My God , this make me crazy !
Binance Smart Chain is also now starting to follow in the footsteps of Ethereum as this coin is also getting really expensive because everyone who owns BNB doesn't sell it cheaply.
Maybe TRON, which is still very cheap until now, because the TRON price is still cheap, below 0.5 USD.
