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).
I think it's hard to hold bitcoin right now, If it's me i will playing safe like sell all my bitcoin and wait until the bitcoin price not decrease again. and buy bitcoin again when the price going up.
Yeah holding bitcoin for a certain period is good, but holding it for a really long time will not serve the purpose, if the value is high its better to sell it and wait for the right time again to buy when the price falls down, and that is the best way to make some quick money from bitcoins.
