What is the best way to hold coins for long term so nobody hacked them.
My list of coins:
Digibite
Antshares
Stratis
Waves
XEM/NEM
What external device can you recommend to store these types of coin?
Is it possible to make a paper wallets on these coins?
for that list, i can give a recommend for you to use coinomy and coinpayments for android phone wallet. i see digibyte, stratis can be store in coinomi, waves can be store in coinpayments. for antshares and xem i don't know where is desktop wallet or android phone wallet. maybe for antshares and xem, you need to install desktop wallet so you can store in that place. i am not sure is it possible to make paper wallets or not because i am not yet to try, maybe later i will try it.
