I save some bitcoin in the online wallet.
Very much common plan.
Why you are choosing online wallet when you have many options of standalone (desktop) wallets.
I'll wait around a few years. and then I sell them at very high prices. I hope my prediction was right and I became a wealthy man because bitcoin.
