I completely agree with you and I do not regret that I do not want to buy bitcoin or ether, I want to earn and to do this I need to take a little risk and buy altcoins at least from the top 10, I can not advise more, but I myself buy and altcoins with a much lower rating.
If you don't buy Bitcoin and Ethereum, then what altcoins are you buying now?
You are also very brave to take the risk of choosing altcoins whose rating is very low, below the top 10 Coinmarketcap.
But sometimes risks are taken for us to achieve greater profits and this is often done by members who have a very strong mentality.
Not only mentally but also strong funds, for example member A has funds of 55,000 USD and member A buys ZZZ tokens which are ranked 500 on Coinmarketcap with capital of 5,000 USD.
Member A still has 50,000 USD left which he is ready to buy top coins, in case the 5,000 USD funds are lost or lose in buying ZZZ altcoins which end up being dumped.
