I Want to know how I can recognize right coin, expect BTC, and ETH, how I can recognize some other good coins?
For me if you follow their project well since its early-stage and knew yourself that it has potential in the future to be a good coin. Just like BNB now, it started with a 1 digit price few years ago and people just ignore it at that price. Since DeFi platforms became popular and binance smart chain network was introduced it soared very fast this year.
How I can recognize when is the right time for buyng and sellig crypto to make most of trades profitable?
No one really knows when is the right timing for this, cryptos are very volatile so you should not be greedy when you should sell. If it is at low price don't go all-in because that particular crypto could go lower if the market is not in good condition.
Is it possible some how exploting some coin and be sure this coin can make 10x, 20, 50x,... in next months?
There is no certainty in crypto. If there is, all of us would probably be rich this time. 10x or more gain often happens in shitcoins in a short amount of time but how will you know that coin will pump like that in few weeks or months. It can happen on good coins but is there anything you can use to predict that.
