These are my main strategies in trading just refer them.
1. Trade your coins vs. Tether, not BTC or ETH
2. Buy the dip (don't panic if you're too late, there will be more opportunities)
3. never join pump & dump schemes
4. Start with a good exchange (this is very critical)
5. Look for a good (research) and relatively active coin (consistent high 24 hour volume)
6. Market cap is not important but coin count is...avoid high qty coins if possible
7. Watch/monitor the charts
8. Avoid "flat" graph coins...look for very erratic behavior...those are your buy/sell opportunities (unless you want to jump from one coin to the other)
9. Do not pressure yourself to buy or sell (i.e. do not have a fixed time period)
10. Don't follow up anybody.
