Your side income can be used for the DCA strategy in buying, so your 0.1 BTC will increase even more, there is no special decision in the investment we run in bitcoin, because the power of maintaining value will be more addictive to buy and the DCA pattern is the most effective strategy possible for us to do, because of the problem of availability of capital that we have. Anyone who is able to take a chance, then he will come out victorious.
When there is more income you know about running the DCA strategy it will be profitable when the price is still low because 0.1 BTC is still small enough if we can still afford to continue to buy it all the time in terms of DCA.
Not everyone can take a chance from now on, but for those who have the courage to do so, of course he will be a winner by being able to hold bitcoin longer by continuing to accumulate.
If you have capital, it's better to apply it to bitcoin only.
