It's not really staying even at $650, the price has only been here for a few days, compared to the $440s for almost a month.
I actually wish I bought Bitcoin when it was at $1, or less.
Similar sentiment here any price under $1000 is still a reasonable price to me as in pre next bull market
That said I got some at the price you mentioned but then it went to 450 to 430 and made me go U_U
Plus the time it takes for money to move from bank to exchange to Bitcoin takes a while but when its in Bitcoin its done
So it is all relative to me
