big yes !
because i was joining this forum since the price of bitcoin 6000$ at the time.
and it was increasing slowly and the last of the year till the beginning of 2018 was great moment.
it was 4 times more expensive than the first price before.
and now. we know all it's getting low price again.
i regret at the time not buying bitcoin in low price. than i bought it in high price.
the next day, the price is getting normal.
i was sock and it hurt.
that's why i stop trading since at the time.
