I am over 90% bitcoin in my portfolio right now. Bitcoin is going to take so many for surprise here, who, some how, still think its old and outdated. That [insert favorite altcoin here] is going to over take it any day now.
In my personal opinion, risk is relatively low for #bitcoin right now, it's pretty damn close to the bottom. As for all the other altcoins...there is really no price floor for ANY of them, even #ethereum. Altcoins = much higher risk, even after 10 months of bear action.
