Hi there,
i'm quite unsure about where to save my btc and eth. personally as i travel a lot i will have difficulties using a hardware-wallet, so i was thinking of a kind of mobile version. is there anything you could recommend?
I am using blockchain.info wallet for my bitcoin and myetherwallet for my etherium for me this 2 online wallet are both safe and secured because you are holding there private keys just make sure that you already save it and put it in very safe place that no one can stole it from you.
These are the main and best wallet to be using for saving our coins, but i think that still there are so many other wallets, like xapo which you can use for saving your coins, in fact you can also use exchanges wallet for saving your coins, but i will not recommend you to keep a big amount in exchange wallet which can not be consider as more secure and trusted.
