Shill me your altcoins and tell me why they're not a shitcoin and why anyone should buy them 
You would notice that most will suggest the top coins in the coin market cap, especially ethereum. Looking at the top coins, Binance became worth more than $1 billion in less than one year, and thats definitely what you look at as investor.If you are an investor who feels that the security of your investment is the most important aspect of all. That is primarily the reason why I also choose the top coins more than the coins that are ranked 1,000th or below. I only have very limited amount of investment and I want to see to it that they are invested into the most secured coins, and that is of course Ethereum, XRP, Litecoin, BNB, and some more.
But there are other investors who are more risky. They choose those at the low ranks and have low marketcaps for a faster growth of profit. That is risky but rewarding in the end if they are choosing right. It requires a lot of studying though.
