It is indeed a very nice opportunity, but i would not trust that much on it. Maybe waiting a few more days would be the best thing to do.
Ethereum is very attractive right now, take a look over it.
Why should need to wait for some time if this is the opportunity to buy with the current price. I cant see anything about ETH right know and sooner or later it will fall again better look for the price of btc.
We should think and choose rapidly and don't hold up until everything is finished, simply ride on the pattern. On this situations that this whales needed to play all the more carefully, at that point give a forceful methodology. Manage this value vacillations, so you should purchase while value is less expensive and never wait btc and eth value spikes higher again.
