There's no such thing about safest and best way to profit with this very speculative market.Ofcourse there would be still a risk
because we cant even point out on which price would be considered to be the bottom.BTC and other alts do always been good on breaking
investors expectations yet it can breakout nor slump its price unexpectedly.Buy low sell high sounds pretty basic but can you actually
apply it out on this very bearish market? Im sure you would be still hesitant.
This advice of buying low and selling high is really not applicable to all coins and it would be very difficult to apply such rule in this bearish market because we have some coins now, that looks like they have already bottomed and would also look like it is the best time to purchase them, but before you really know it, it keeps going down in price.
For those coins, the best time to actually trade them is during the bullish market, but exceptional of Bitcoin, Bitcoin can be bought at any time because no matter the drop in price it may have, there is always going to be a short period of time for it to recovery which whoever is able to buy at dip price them would be able to make money within the shortest possible time, which I think maximum would be 4 weeks.
