New projects are almost comes on the BSC wallet or on the TRON wallet becasue of low fee so in future the BSC wallet is good and secure like the ETH or not?
Well, you are making a big mistake if you are referring to Binance smart chain and Tron blockchain as a wallet, wallet is different from a blockchain and this I think you ought to have known regardless of how newbie you are to crypto..
And just be clear, transactions on Tron network or blockchain isn't cheap as many assume or presume, my recent experience with this blockchain got me really upset to the extent had sold everything I had on that chain and with drew the proceeds and deleted the associated wallet.
One of the cheapest blockchain networks I've used or transacted on is Sui network, follow by Bsc or Solana..
Speaking of security, ethereum is secure, and I do not think Bsc can ever match up to the ethereum's security standards as long as blockchain is concerned.
