Yes I think if you invest in Bitcoin when its price will increase then it is good for you. This is the only opportunity for long term investment. I think Bitcoin is the only safe currency, if you invest in this currency then you can make your future bright. There are many who want to buy it when the price is high but they may not know that if you buy it when its price is low then you can earn much more profit from it in the future.
Getting yourself worked up trying to outsmart the market is useless because Bitcoin is still very cheap at this present price if compared to how much it might get to in the future, so waiting for a dip or trying to buy in a favourable term as you think is another way to waste valuable time and buying opportunities, so as long as you are thinking long term, just buy once your discretionary income is available, in the future you will be happy with yourself that you made the right decision now that the opportunity is still available.
Now folk are being careful not to buy at the top think we might have already reach it , and this is quite funny because you having such mindset shows that one ain’t up for it (bitcoin investment). Because bitcoin all about long term so doing all those time one have to focus on accumulating for a while .
May be when you have gotten enough stash (which might not be easy ) but by following the right principle you be able to pull it up and things will definitely be smooth too .
