JJG could be a whale then
It seems to me that the practice of buying on the way down and selling on the way up is a "well-established" practice. It is certainly no original idea from me, I just happen to spout it off on a regular basis because I remain pretty strict in continuing to follow such a practice and I believe that it works quite well, especially for any asset that you expect to have strong long term fundamentals (i.e. bitcoin).
Gosh.. actual "whale" status would seem to require several thousand coins, no - unless the "whale" figures out a way to manipulate with smaller coin quantities, perhaps using smaller exchanges, and of course, being able to influence others through information could cause a lot lower coin requirement to reach "whale" status?
