I always appreciate when people (including newbies) make their own decision when it comes to investments. Relying on others opinion or information might cause a loss so it is none other than a gamble. You sold your bitcoins when price was on the peak and you made profits and now you can decide should you buy bitcoins again at lower price or not.
Personally I like to suggest everyone not to have any plan to sell instead of that, plan up to use your bitcoin for your future.
It might prove beneficial for one time or two or three times but how long someone should remain dependent? I think if someone has some money to invest then he should spend his equal time in order to conduct research. Investing money would give you one time returns but investing time would give you constant returns.
