Bitcoin just broke the 4000$ support . It was a really strong support . This time we didn't observe a strong rebound . Goldman sachs planned a bitcoin price around 2200$ . Before that we'll have several supports . Personnaly i think 2200$ is really low but who knows . This market is highly manipulated and thanks twitter and other medias a lot of novices started trading cryptos so a panic movement is possible .
I'm out of cryptos during the fall except for walton and neblio which suffer too but have a small marketcap , just arrived and have a lot of potential . Don't try to trade altcoins while bitcoin falls . Usually altcoins follow bitcoin's movement with amplified strength .
