What is your opinion about this?
Like trying to catch too many things at a time or focusing on too many things at the time can make it difficult to catch one so also does trading so many pairs makes it difficult to understand anyone in particular when you are a new trader. The traders who trade many trading pairs, did not always start off trading like that, some of them focused on one or two trading pairs for a very long time before trying out others. If you are planning as a trader to trade multiple pairs you have to start somewhere and that starting somewhere means you have to start from trading one pair first before adding other pairs to trade.
Everyone has their own ideas about trading and their own strategies. I don't think if you are new to the market, you should bet on more coins or just bet more on one coin. You should invest little by little in different coins maybe one of them will turn into profit and the best thing is that when someone is new in the market he should first understand the market when he enters the market. He should understand and know about coins, which is good, which is bad, which is going to profit, and which is going to lose. Only after that, he will trade, and then he will be a successful trader.
Besides, if without knowledge he invests money in a single coin or invests money in thousands of coins, it will be a loss, because trading is not done based on luck. It is very important to understand the market and trade at the right time. Any person who thinks that he can make a lot of profit just by trading is just a misconception and nothing.
Yes, it can be said that if you are an expert in a coin, you have followed its movements, and you have analyzed its candles well, then you should invest money in that coin that you know well.
