For me I'll choose trading cause I can't wait too long and it's what needed in holding 
). With trading I can earn Bitcoin very quickly but with holding I need to wait until the price of Bitcoin increase. But trading require more than holding, if you want to earn Bitconi with trading you need to have a lot of experience, trading skills or maybe a trading signal bot 
Bitcoin is gaining more than any other asset in the world before (I am not counting illegal stuff, short-lived bubbles or dubious financial schemes).). With trading I can earn Bitcoin very quickly but with holding I need to wait until the price of Bitcoin increase. But trading require more than holding, if you want to earn Bitconi with trading you need to have a lot of experience, trading skills or maybe a trading signal bot In last 30 days we had +56.50% price rise of BTC - so are you seriously saying that holding bitcoin to get 50% profit is not good enough?
I would rather have solid 50% gain than even higher but not certain profit.
