The best moment to purchase bitcoin was last year, when prices were even cheaper. Now it's good too, but not the best moment, though. Anyway, it's still not too late. Everyone can still buy bitcoin and prepare themselves for the pump season that can happen this year or in the upcoming years. The market is looking better each new day and it would be great if it continued like this, but investors must be careful, because we are talking about a tendency that has started few days ago. It can be a bull trap, so beware, and don't expect immediat returns from your new investments.
