Buy low sell high, but it's better if you have around 50. But that's the only way unless you want to try gambling. If you're looking for profit, this isn't the forum you want to invest big. But you can try a good gambling site.
Price is highly volatile and unpredictable. A burst bubble can instantly get you negative profit. Gambling wise, you are more likely to lose in the long run than gaining profit. If you're talking about investing in a gambling site, every legit gambling site has a negative EV, aka. house edge. It should in the long run, get you up by 1%. But, a whale (though he lost some BTC afterwards) can easily wipe out the bankroll or even an exploit.The more important thing is to find a trustable BTC gambling site which allows investing which is hard to find. The only trustable gambling site I can think of is just-dice which accepts clams.
. But for now it is still will be short term investment that many people are rely on it to get profit everyday
