Here's the example of how I invest/trade: I've done a lot of research on 2 coins: ETH and NEU (Neufund). Both have solid use. My team uses Ethereum for software development so I follow closely it's network usage, and I know pretty well how many companies use it for various purposes. Neufund is the first Equity Token platform, it's economics are clear to grow and generate income, I follow it's channels closely and know what's happening. Besides these I also own Bitcoin for diversification and cashing out. Besides these that I know well and follow closely I do not buy any other coins, I only earn tokens of my clients through work. When any of my holdings get to gains of over 50% I start selling them slowly, to USDT or to other tokens if they did not grow as fast. For example I sold ETH for BTC when it reached 0.1. Then if the coins drop over 60% of the peak, I start buying them. I never sell on the downturn or buy after token is over 80% of it's historical high.
