Of all times to buy BTC, now is actually one of the better moments. The froth in the price has come out and it's much more reasonable. Noone knows if the price has finished it's decline. But there's no doubt this is a better time than just several months ago.
You know what you gotta do then don't you? Buy that DIIIP! If not, set on the sidelines idle and which the sharks get in at the best price. Not sure whether we are in a full bear market or just still the correction phase from December's bull run but I am excited to see what plays out next 6 months.
Yup, investing is all about buying when everyone else is starting to panic and sell. You will probably never "paint the bottom", but that's not what matters. You have to be a contrarian to make money: when others are fearful, be bold.
