MY WAY OF OPERATING.
1) WHEN THIS INDEX REACHES GREED, I TAKE THE PROFIT AND WAIT FOR THIS INDEX TO FALL.
2) I USE THE SAME PROFIT TO REINVEST WHEN THIS INDEX IS IN NEUTRAL OR IN FEAR. I DON'T NEED TO BUY USDT OVER AND OVER AGAIN.
And I have made money so easily. You need patience and wait until this index reaches a suitable level, to reinvest only in the top 20 coins of CMC100 that are not risky (that are not going to become 1/10 in a short time). I never invest in high-risk coins.
Slow but steady always wins the race.
