I mostly store my bitcoins in an online wallets. I think that is the best option to store you Bitcoins. I like the online wallets, because it is so nice to work with it.
I hope later that more people will use the online wallets more and that Bitcoin will becoming more popular in the future, and we all hope ofcourse that the value will rise too.
Yes. Rising of bitcoin price is highly based on using of bitcoin, more people use bitcoin, demand bitcoin, then bitcoin price go up, and online wallets are good for storing bitcoin for me too, I personally use online wallet Xapo for storing.
