think the best is to hold bitcoin.
specially right now when there will be soon a halfing and price seems to be in a bullish mode (of course to trade into other coins is a good thing too, but in my opinion you need to hold coins with a longterm vision, and always have bitcoins beside).
Acquire more coins now as I consider today's price is cheap and any price below $400. Soon this dumping scenario will end and.get ready for bitcoin price back in action while halving comes closer.
