So low-initial-capital businesses would be like online reselling, youtube channel/streaming, 3D printing trinkets, shit like that? Giggish stuff?
Those stuff— the "giggish stuff" that you can attempt to slowly but surely grow into a bigger sized and more sort of "professional" business that's not-so-"giggish" anymore.
I get that you're skeptical of the interest-earning platforms but since you're intending on holding your coins for the long term, why not allocate a portion of it? There is huge potential for gains especially since you're just letting it sit there. Nothing ventured, nothing gained.
While I'm personally not for those kinds of platforms, if I were to use them, use only a small portion would definitely be the way to go. Though of course, allocating only a small portion means that the annual yield is going to be really small also, to the point that it might not be worth using them in the first place.
