Of course don't forget that shorts building up and price not moving down is not a guaranteed indicator that price will go up. Bears can still win and push the price down in the end and close their positions normally. But.. if bulls manage to make a push, it's a very bad situation for the bears, as all of the will start closing their shorts together (= buying).
BTC shorts are also on a rise, with BTC daily touching oversold level, history shows that we always had a rally after that. This is a good time for long EOS position imho. If you're not sure about that, just wait for the squeeze pump to enter. Also EOSBTC is in atm (0.00160 - 0.00167).
