Lightning would have been good, but I have one big problem: the value. 1 BTC ≠ 1 LBTC. Because of this, it is possible to lose a lot of money due to price fluctuations.
AFAIK, most exchangers and exchanges have the same value when withdrawing/depositing through Lightning, the only difference is the fee.
Are you perhaps referring to an altcoin named Lighting Bitcoin with LBTC ticker? Because that's not the Bitcoin.
