Buying bitcoin is not really an issue, but being disciplined not to sell it off in a little provocation. Now, we buy and buy more because I have come to realise that bitcoin is closely a one way project, always on the rise. Learning about bitcoin from a trader is one of the worst hurdle anyone can have in the area of bitcoin investment.
According to the rules, it must be like that, if you are disciplined even though it is not very routine, if divided on average you will get a fairly high price because the purchase of course varies in number every time.
For other people's opinions, I think it's enough to just listen if it's good, just adjust it to what you have learned, especially in this thread, both in terms of technique, pattern and duration. many have great experience and are also successful in implementing it.
Discipline, risk-management, and a straight-up plan.
If all of these are there, an investor has nothing to worry about, be his investment big or small.
