MINING is a sure thing, its called a positive sum game.
Trading is gambling, its a zero sum game at best, but almost always the house ( exchanges ) wins, Generally most trading is a negative sum game, everyone eventually goes broke who trades.
Smart people mine, albeit BITCOIN is no longer profitable to mine, because U can't compete with chinese who have access to free government hydro, alt-coins are very profitable
Losers 'gamble,
If U want to make money trading, then be the GUY who creates the shitty ICO and sells it to losers.

Traders bring NOTHING to the bitcoin table.
Miners are the backbone of BITCOIN.
RICH people use BITCOIN to hide and save their money, and to hedge against the upcoming collapse of the USDollar. Chinese also use BITCOIN so their money can escape mainland china. Actually its harder for your money to escape the USA, than for Yuan to leave China ( limit $50k day may leave HongKong ) [ Last time I tried to wire USA to HK my bank in USA refused ]
Rich People are WHY BITCOIN trades for nearly $7,000 USD, Traders are why the volatility is insane.
In a perfect world SATOSHI would have forseen this and figure out a penalty tax to disenfranchise trading, say a coin that flips more than x times a year goes to zero, we can only wish
