There is no right time to making any investment. All time is risky. But then, life is all about taking risks. If you sit and wait for the best time, you may just wait forever because even when others will think is a best time, you will still be waiting for another best time.
To me, this is the best time to invest in Steem because I may not be able to afford it if it goes higher which is very likely to happen.
Don't wait for a best or right now.
The best time to invest in Steem was when Steem was started, the second best time is now. Take calculation action/risk.
