Firstly, Bitcoin is not supposed to be any investors main source of income. To invest in bitcoin, one must have a stable source of income where he earns, monthly, weekly or even daily. This allows someone to be sure of the next moment. To diversify your income is the reason for investing in bitcoin. So if anyone is seeing investing in shitcoins as diversification, then he or she does not understand what he is doing or greed is taking over him. Bitcoin is a stable coin which has survived years of tests. Anyone investing in altcoins and shitcoins is already a trader because shitcoins cannot be hold for long to avoid loosing all your money.
Maybe I think you should read this back again because I can't remember Bitcoin being a stable coin, Bitcoin is not a stable coin you should note this because it has it's volatility pegged to it and the reason why new investors are increasing every day, if Bitcoin where to be a stable coin it wouldn't have gotten to where it is today, when we talk about stable coins we need to consider coins like usdt, USD coins.
