I'm glad to see you're making money now and trust the future of steem (I trust it too), however:
Gamble: "To bet on an uncertain outcome, as of a contest. To take a risk in the hope of gaining an advantage or a benefit."
Invest: "To commit money or capital in order to gain a financial return."
Gambling is entertainment, investing is business. Investors are risk-averse, while gamblers are risk-seekers.
Have been following since you moved to steem... you are a speculator and a gambler, because you cannot be 100% sure it will work.
Don't be too greedy man, don't spend "all" your income into steem and save some for a disaster recovery, because you never know what awaits you tomorrow.
