Mean reversion is where the investor assumes that the price of a coin will remain at an average price level over time.  Upward trends, and downwards trends, are expected to revert back to the average over the long haul. This means you need to know the charts well and be able to figure out what the average price for the cryptocurrency you intend to trade in. When the coins are less than the estimated average that is when one wants to make a few purchases. When the price is higher than the average it is expected to drop back down to the mean price and that would be the time to sell.  Of course, figuring out just when to sell is the trick, and that is where the gamble comes in.

You need a trading plan. You can basically consider it to be a blueprint for success. Your plan has to take everything that you can into account like entry and exit of money, risk management, time frame and even position sizing. Without a plan and too much emotion, you will be gambling instead of trading and you will never know how to improve your skills to become better.
Let’s say on January 2, 2017, you owned $1,000 and exchanged it into euros (EUR) with another market trader at a rate of EUR€0.9565, leaving you with EUR€956.50. Then, on November 24, 2017, the value of the US dollar had fallen from EUR€0.9565 to EUR€0.8380, so you decide to exchange your euros back into US dollars. After finding someone willing to sell their US dollars for your euros, you carry out the exchange at the new price. Your EUR€956.50 is now worth $1,141.40, leaving you with a profit of a little more than 14%.
There are many groups on Facebook where you can find likeminded folks who will happily talk crypto all day but the problem is that 99% of these groups are filled with people who have only a very basic understanding of cryptocurrency and the knowledge available here is not particularly strong. I have recently left almost every single group on Facebook as, in my opinion, they are largely filled with FUD.

Now that you have identified the coins to invest in, you need to find an entry point for your investment.  Technical analysis has always been the best strategy for finding an entry point when investing in financial assets. The best way to use technical analysis in finding an entry point is to understand candle stick patterns. For instance, if you are looking to buy Bitcoin, then a bullish engulfing candle stick pattern on the weekly chart would be a good indicator that it is time to enter the market.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
