AFTER WAVE C
According to that webpage,

After wave C, we go LONG when RSI(3) crosses up level 30 in the H1 chart.

From wave C, we move in a zigzag pattern up to the level of wave A.
Then, another zigzag move takes us up to the level of wave B.
After that, we continue the zigzag rise toward the all-time high (around $4,381.64).

And from there — we go to the moon!

Also draw a Fibonacci retractment from the ATH to the low of wave C.

Best way is to BUY only.
