If people like Warren Buffet thinks bitcoins are not good investments, you can just imagine your average Joe. The irony is that while these people laugh at Bitcoin users when price are low, it's usually these people that feel left out during hikes.
As for sore losers, if they bought high without checking the record lows first and how long bear trends last, then it's their fault, don't blame Bitcoins.
as long as we are not sure, of course do not invest here, because it will bring disappointment. we must really determine the attitude according to personal analysis. Current prices are low, but not necessarily the same as other people's views
when you decide to invest, I suggest you make a long-term investment and you should invest in potential coins such as bitcoin and some other coins that have limited supply because only a limited supply can make the price expensive.
