I use a cryptocurrency wallet, it is very comfortable to use it, especially if you need to make a lot of transactions a day. First of all, I like that there are no restrictions in transferring money using cryptocurrencies and it is anonymous. I always need to make big transfers in different parts of the world, and by transferring it with BitCoins I can do it easily, without using intermediate like banks that take its commission. I usually use BitCoin, but last week I started to buy more , in my opinion, it has big chances to become expensive.
I can agree on that, but crypto wallets are not the only one acceptable option for the financial operations, especially if we talk about online entertainment like gambling. Take a look at this bitcoin gambling web resource, to understand how cool it can be, when you not just spending your BTC online, but also have a lot of chances to win some of those.
