Maybe we can say right now is the end or game over for bitcoin and altcoin, how come bitcoin at last end year could be on $15,000 and now have drop lower than $4,000. You can left or stop investing your money at bitcoin and wait until bitcoin price is higher.
maybe more precisely the end of your investment is not the end of Bitcoin because in my opinion Bitcoin is still alive it's like limping. I'm sure if bitcoin will find a way to grow again as it used to. if you wait for Bitcoin to increase and you have just started investing, you will never experience the satisfaction that can only be obtained if you survive or buy bitcoin now.
