I spent a lot of effort on learning about trade. I have also experienced many psychological feelings, ups and downs, so I would like to share from the bottom of my heart some tips for beginners or amateur traders:
1. Trade only 1 pair of currency: usdt and altcoin
2. Invest in good altcoins only (1-5 crypto), focus will bring about higher chance of winning. Treat btc as an altcoin and make a speculation with it. Learn how to identify a good crypto in order to hold the coin whenever the storms come.
I agree that the fewer the coins a trader is following, the more focused and up-to-date he stays - no need trying to be jack of all coins and master of none. The are many coins out there, but I suppose the choice of USDT here, must be because of its relative stability and especially the hedging opportunities it provides, when the market start spinning on its head and which it does quite often.
Btw OP, I don't see how the points highlighted are linked with the topic!
