So i guess its not worth selling btc which are less as the fees will be the same if i sell 100k satohis or 1btc.
What is best wallet which you can suggest. I checked the thread in beginner and help about wallets but there are many.
It is better to store first huge amount of bitcoin before you withdraw it because the transaction fee right now is too expensive because of traffic on transaction which cause force all user to set high fee to prioritize it by miner. Try using blockchain or electrum,but again, all wallet has a transaction fee. Just follow my advise.
