Investing isn’t poker or rather it should not be a gambling game. If you go all in with investing in an asset or two, you are almost certain to lose everything, it is just a law of probabilities. Diversify. Do not believe anyone who tells you otherwise, ever. Of course this new generation’s first instinct is to go all in and then when a correction or crash sets in, they lose everything. They then go away and never come back. It’s a never-ending cycle.
Daniel Defoe, the author of Robinson Crusoe, wrote a pamphlet in 1719, “The Anatomy of Exchange Alley or, a system of stock jobbing. Proving that scandalous trade, as it is now carry'd on, to be knavish in its private practice, and treason in its publick.” Does the sentiment sound familiar? I have republished some books from the turn of the 19th century with a preface saying basically, “Do you notice the stock market is basically unchanged even after more than a 100 years of historical turmoil?” The scams and attitudes of the market and its participants are still so recognizable after over 100 years you are left to wonder if the billions spent on compliance on the worlds bourses are not a complete waste of money.
There are so many hoops to jump through to set up for mining and each coin has its quirks. The power of your machine and graphix card and your power consumption are all important. My friend mined for 8month Eth and only made couple of hundred bucks by time you subtract power useage etc. He already had a powerful machine used in film industry for video graphix just sitting around so he thought he’d put it to use over that time for a laugh and see what happened. It took many hours messing around to set up and occassionally nursing it over that period. Of course he had to use his machine also occassionally which compromised the performance.

Don’t be greedy. No one ever lost money taking a profit. As a coin begins to grow, the greed inside us grows along with it. If a coin increases by 30%, why not consider taking profit? Even if goals are set to 40% or 50%, you should at least pull out some of the profit on the way up in case a coin doesn’t reach the goal. If you wait too long or try to get out at a higher point, you risk losing profit you already earned or even turning that profit into a loss. Get into the habit of taking profits and scouting for re-entry if you want to continue reaping potential profits.
