Reading the replies of OP it seems that he made up his mind and never call it a quits and just planning to hold some and diversify the rest and it's a good and wise move to do. Cryptos are just starting its era so it's too early to call it quits and I think no one in the right mind will quit when he knew that he can profit big.
Yeah, common ! I mean, I see no reason for OP to quit too. He has built a good start that some of us wish to have got to & with 26 age, he has fresh energy to go all out for diversification. As rightly said , cryptos are just starting up, he could build more money since he already has the capital .
In my view, I think he should split into two, invest one part in real estate and then sell off some of the coin that have got to there highs and then buy cheaper coins with good tendencies for growth in the future. Meanwhile, I hope he is keeping his securities and code save, also disclosing to a trusted party - just incase.
or he can invest in both, blockchain powered real estate technology. A lot of them are appearing but few ones are worth the time to invest in. (e.g. Proppy, AQWIRE, Needacoin) imo though.
