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.
Well, I may have used the term wrongly but I may not also be too wrong because what I mean by that is the ability of bitcoin to be resilient and bounce back after a period of volatility. Bitcoin volatility is it's strength, and just like every other supposed stable coin, the USDT, USDC and every other one as you've outlined which also have their minimal volatility as regards every other currency.
we don't have to wait till will have a stable source of income prior to getting started
I still disagree with this. Anyone who ventures into bitcoin investment without having a stable source of income may not be able to survive in it. The ability to hold your bitcoin for long depends on how well you can handle your financial stress without having the option of selling of your bitcoin stash.
You can only have a discretionary income when you have a source of income. Discretionary income comes from stable income because it is always relative to your next income from which you can make out your discretionary income for your next DCA investment. No successful investor who achieved that without a stable source of income so far.
