Btc is $6.5k today. It will not fall now. So buy at this moment and at the last of the year you can earn huge amount of profits because it will touch $20k at the end of the year. Now don't wait for btc to fall to $5500, it seems to be impossible. I am very sure that btc will not fall from $6.2k now, but still don't wait , buy btc at this moment and wait for the peak prices.
