You are very lucky to have utilize the opportunity when the Bitcoin price was that low, it seems you invested huge for you to have seem such excited, actually it was wise for you to have invest on Bitcoin then because there are people who are still waiting for the Bitcoin price to drop more before they could invest and the price keep going higher so I believe that every moment is actually good for people to invest on Bitcoin.
Every time the Bitcoin price is good for entering Bitcoin, but you also have to consider whether you are entering at a price that is good enough to support the profits you will get. If the target price you want is still quite far away or at the new ATH the current price is certainly still more than half of it. We will see bitcoin rise higher from now if it holds for the long term. You only need to make purchases in stages to get a good purchase price, it must be managed well.
