Just imagine the price of bitcoin in 2016 and 2017,it was enormous right so you need to wait for your time to come.
Don't forget that, bitcoin price of 2018 January and now, after 9 months of time it went down rapidly and lose more than 2/3 of investment so far. Long term investment is better if you can forget it for more than 2-3 years. Otherwise you will end up with lose of money.
I think that the profit that bitcoin can bring to you is worth it to wait a few years. But if you need a quick profit, then you better invest in promising altcoins
Still the question of how well you understand the system, before investing with anything you should prepare yourself taking the risk, crypto trade can bring you profits in different ways, if you can stand and aimed for maximum profits you need to learned lots of patients as waiting game is a big factors but if you want a bunch of short trade and daily results taking a big risk shorting the market, better to make sure that you can fully afford whatever it takes
when results happens.
