This is really the best time to invest in bitcoin. I told someone to invest when it was $16k. Assuming he did he would have been a happy man now that it's 19k. Even if it won't get to 100k I really believe in the coming year it might get to $50k. It's really best to invest in it now than when it's $50k.
People who are outside (people who don't know much about crypto see Bitcoin as a negative investment because of recent occurrence but that's why it's an investment. There's no investment without risk but because there's risk doesn't mean we shouldn't invest.
In my opinion, the all time best period to invest in bitcoin was about 10 years ago and the next best time to invest in bitcoin is now. But a valid point to remember is to have the ability to hold onto the coins for a long time. Thats when investments(bitcoin or otherwise) usually yield maximum profits
Theres always some risk to bear when venturing into investments and that should not deter the young and inexperienced investors to be able to buy and hold bitcoin for the long run.
