Bitcoin mining is gambling. It is pure chance if you discover a block or not, no skill is required.
A mining rig merely improves ones probabilities, akin to a sports betting hotline predicting outcomes/ card counting etc.

Bitcoiners invented very misleading terms ie "mining", calling bitcoin a currency etc. To give themselves some perceived legitimacy.  This has led to major confusion amongst governments and users.

Mining for bitcoin no different then playing roulette.

This would be great news for Canadians since gambling is not taxable in Canada.

The following is a story from trading stocks today. If you are not interested in trading stocks and prices it might bore you, I don't know.

Hey guys. Made 2 big mistakes today trading stocks. When I finally got around to checking my brokerage account's watchlist, I saw that ISR was up from $1.10 to $1.93. This was already around a 70% increase, which in my opinion you don't see very often. Usually if I am late to the party and a stock has already went up 70%+, if I jump in and buy, everybody already has sell orders executing because of the day's rises, then I get burned. Today I had seen the huge volume in it, this was around 2 pm, and the price at $1.93, I set a limit order to buy at $2.07, but watched as it climbed and climbed. Was going to raise my buy limit price to $2.10 but then decided to watch it live on my phone while I had a "market" buy order ready to click on my laptop as I saw the price drop to the lowest possible. Anyways, somehow my waiting hand accidentally clicked "buy" on my order and I bought 75 shares for $2.38. I thought to myself- Damn it! I thought everybody was going to continue selling and I had accidentally bought it way too high. So then I waited. I saw it steadily rising a little at a time, so I figured if I could pull off $2.54 a share I would be able to squeeze out a little in the positive. So I waited and waited some more. Then I saw it start to rise pretty fast. As it neared $2.50, I went to again cancel my limit order of "sell" for $2.54 and try to squeeze out the highest market price available. Long story short there- The price continued to raise. I ended up not cancelling my sell @ $2.54 order, it executed without me knowing, and then I sadly watched as the price went up further from $2.54 topping out at $3.04 for the day. It opened at $1.10! This stock went up from $1.10 to $3.04 today, nearly an 180% increase and nearly tripled. I kicked myself for not going all in at $1.93. Today's volume was around 87.39 million.

Anyways, does anybody think ISR will continue to rise tomorrow? @5thStreetResearch do you have any thoughts on that stock? I bought 58 more shares after-hours at $2.50 with money I will have settling tomorrow.

Variations in share price tend to depend on changes in the margins

True, but many of the marijuana companies are moving up everyday towards full reporting. Props on working for that San Fran hedge fund too. Basically my dream job is day trading, with my own money.
