I am not so much on the techie side so pardon the noob question. I am planning to purchase an external hard drive so I can just install there my wallets and for mobility. Is this advisable? If not, please give alternatives for someone like me who's always on the go. Thank you in advance!
While that would most likely work, There are better approaches to keep disconnected wallets also.
for ex:
In the event that you demand electronic capacity, I'd prescribe a usb-stick over a hard drive. Likewise, don't utilize the bitcoin.org programming for that wallet, it's a genuine annoyance to utilize that way. Multibit,for case, would work better.
