BULL'S GROUP - always putting money into the market and does not take out often, more like long term investor.
BEAR'S GROUP - always taking money out of the market often, more like only interested in making money in a short while, i mean short term investors.
I was in those two groups.
I invest in altcoins to earn in the shorterm trade. Usually I buy in the finish initial coin offering , because the price is cheaper and drops right away. And in bitcoin for longterm holding I usually have 3 to 5 months before im selling bitcoin. But when the price goes up I sell it right away.
