Dumb panic sellers
Nope. As you can see right now, there is a whale dumping up to 5 consecutive batches of 64 BTC (that's some real money there) fully manipulating the dump to way under 2210. And he wants to be know he has at least that many to do the manipulating, so he makes it obvious to everyone. He may have, besides those 300+, many hundreds more. And that's just a single one.
It's children with millions of dollars playing games. It will not affect BTC in the long run but, for the time being, these are very dangerous waters for the small guys. Thread with extreme precaution or don't thread at all and don't even look for a few months. Or years. BTC will be quite fine.
And you will not be burned.
And by all means follow the number one rule on investing: Never risk what you cannot afford to lose.
And the second one, even more important: There's always tomorrow. Make sure you'll be equipped to go another round.
