Some explenation. I sold all my alt-coins, I wait for the bitcoin to stabalize. That's my personal strategy, because I always want to minimize my risk. There is a huge change I can buy my alt-coins a lot lower if the bitcoin drops. Otherwise I just pay a little bit more and take my lost.
But I always keep in mind in my opinion the whole cryptocurrancy world is one big bubble. That's why I always sell when bitcoin drops below mayor support level. Remember it's better to save ur money, their will be so much opportunities to grow ur stack it's not worth the risk.
