It is always risky to put your money in volatile currency like Bitcoin.It may increase your capital to many folds in a few months and the same time it can decrease your capital many folds. Think about the people who bought Bitcoin at $19K and even after 1.5 years they are at less than 50% of their capital.
I am not against investment in Bitcoin but people should always calculate the risk before investment. In my opinion investment in Bitcoin will be fruitful in coming years. If someone invests amount for 4-5 or more years, he/she may get good return.
The only time that you get into risk in bitcoin is when you invest when bitcoin is already at peak, and that is the very big mistake that people that invested at that $19800 did, which is why every investors needs to first study the market situation first and examine it for them to determine when they should enter the market.
The best point that we should always make our investment is when bitcoin is in a dip state, like the way bitcoin plunged to $8k of recent, that should actually be the target of nay investors, and not wait until bitcoin is getting to $15k before they buy, when bitcoin is getting to $15k and above, they ought to have started limiting the amount they invest in it for safety purpose so that it would not be another peak that they are investing in which will now become the risk part of it.
