Gambling with Steem and Steem-Engine

Well reading posts on Steemit I came upon one that said that there was money to made on Steem-engine trading with all the Tokens there against Steem, you know buy low and sell high, well I have no idea about what low and high is on Steem-engine but I thought I was going to try it.

So I sold some tokens I had lying around there doing nothing and I got 45 Steem for them, now I had Steem lying around there doing nothing because I couldn't figure what to buy, so I did what I always do I started gambling on Kryptogamers with blackjack, my tactic is I start betting one Steem, double each time I lose and go back to one when I win. I only win 1 Steem each time but it adds up, and if I get dealt 21 I win 2.5 times my bet.

Well I was doing well until I got to a game where I had to bet 32 Steem, if I lost that one it was game over because I would have been left with only two Steem, I really thought that was it. Fortunately the dealer gave me 20 and he busted so I came out multiplying my original 45 Steem to 70 Steem, a very good day.

But really what I want of do is play the game of buying low and selling high looks like a better gamble to me but I have no idea what to buy or when to buy and even less of when to sell. I guess this could be called investing only on a very short term and I have to do this before I lose it all again on Kryptogamers.
