How can i sell my coins from my wallet (i mean how can i get the money in my account) ?
I use Trustwallet if that matters.
P.S. (sorry if the question sounds stupid , i'm new in this investment thing)
Trust wallet is multi crypto wallet which means you are holding multiple crypto currencies.
First of all I advise you to sell your all coins which you wanted to convert into BTC first which can be done with swap option or you can convert them in traditional exchange itself like Binance,etc.
Then sell your BTC for fiat if it is supported on exchanges or move coins to LBC and sell it for cash.
