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 can say that I am a crazy long term holder, and I really regret it especially last 2017 Bullrun
I have alts from airdrops that already had value before but did not sell now its a garbage in my wallet.
