I just might agree on you selecting DeepOnion as one of the best altcoins. DeepVault, DeepSend are crown of DO what i know of. Im nostalgic about TOR, and the working principle of Onion makes me eager to select it as best altcoin in 2018. Idk what else they have, ill have to check it out.
Im not sure about Ripple, still its attractive. Yet, Deeponion is a fresh start and much more appealing to invest.
yes I certainly agree with you about DO but the reason why I choose it as my best of 2018 because the features in posses and ripple because I heard news that ripple was use by banks I just don't know yet if it was true and ripple is rapidly raising up in the market
