I think it's a good idea to invest in Bitcoin at the moment, later when bitcoin prices are stable, you will get profit from it. that is what I thought.
You are right it is good time to invest our money to bitcoin because price of bitcoin is getting high and low, but now a day price of bitcoin is low so best opportunity to buy some coin and hold, later on price of bitcoin will be high and then it will be all profit, same as you I think bitcoin investment is the best source of earning money, so when price of bitcoin will be high so we will get profit.
