This is totally amazing and of course there are some questions:
- Where does the money come from? From institutions and banks? From large investors?
We don't know, perhaps it come from any one of them.
- Why do nearly all Altcoins quickly increase at the same time?
Because Altcoins follows Bitcoin prices movement.
- On which exchanges can be trade so much money in such a short time?
Usually top and reputable exchanges.
- Who knows about such breakouts before?
- etc ...
No one knows because we don't have crystal balls to predict some breakout.
In addition, BTC was in a downtrend before 24h and close to a DeathCross. The resistance was very strong and yet my short-possition was blown up like a nuclear war star and totally shredded. Of course everything is possible, but it is incredibly impressive how much money flows into the market in such a short time and apparently everything at the same time and with nearly all Altcoins.
The last time we crossed a Death Cross, bitcoin also made a significant gain. So perhaps it's just a coincidence or just people FOMO'ing resulting in a massive spike in the price.
