Today is the best day to buy hard really. No one can catch the perfect bottom price. But anybody can make Avg lower price. So, around 220 to 230 USD is the best price to enter into bitcoin for long term holding.
if i had spare cash rn, i would trade it all for btc. the prices have been pretty low recently.
That wouldn't be very smart, remember to diversify your investments because with BTC you are more than likely to be wiped out if something goes wrong.
