hi everyone. i did a paper wallet from this website : ripplepaperwallet.com 1.why is the public address more secure (longer) then the secret key ? is it make any sense ? 2.i tried to send 8 ripple coin to the public address but it would not let me : "address invalid for xrp wallets" or something like that. the address is correct after i checked 20 time and copy paste it. is this website ok ? did anyone worked with it ? 3.what app to use after the ripple coins will be send to the paper wallet to take them back from paper to online ? i want to test if i can put it on paper and take it back before i invest on ripple coins. thanks alot!
