Blockchain is primarily a cryptocurrency exchange wallet. It is a system developed by the world's leading banks. It can be used for both web and mobile devices. I think it is reliable because it is based in Luxembourg. One of my first cryptocurrency exchange wallets. 2-step verification process as an iOS user. It has a very simple interface but one of its shortcomings is that it supports very few cryptocurrencies. I also recommend that you do not keep too much money in your wallet. It would be better if you split it into different wallets. If you are just starting out, this wallet is great for you. It does not charge commission when sending and withdrawing money. One of the most important features for me is 0.024% commission when selling BTC and 0.014% commission when buying. Live support works very well. If you ask me, I recommend you use it.
