Easiest online blockchain.info but only for small money to keep there. But it has additional fee for transaction, so you better google and choose for your needMore secure desktop wallet like Electrum.
Whatever you choose, choose only most known ones, coz less known could be a scam.
Thanks!
Your recomendation is very actual for me. I don't have lots crypto in BTC so I use blockchail.info.
At the same time things are getting better, so probably Electrum will be necessary.
