I don't think you're being fair. Yes you are doing something by putting a little money into Bitcoin here and there. You are supporting Bitcoin because you want a better monetary system that isn't based on debt, and isn't confined by borders. When times are lean then it makes sense to stash something valuable away, until it becomes worth more. When the value appreciates again, Bitcoin holders can use their increased purchasing power to support businesses that embrace crypto, rather than cash out. That's what 'many around here' are waiting to do I'm sure.
Buying a bitcoin and doing absolutely nothing with it for 10 years is about as useless to the bitcoin ecosystem as completely ignoring it.
You dont support bitcoin by wanting a "monetary system that isn't based on debt, and isn't confined by borders" .. thats called dreaming. You can support bitcoin by actively seeking out ways that you can integrate bitcoin in your daily life, and maybe provide services to others using bitcoin.
Also, when times are lean, the LAST thing you should be doing is putting what little money you have into a highly speculative and risky 'investment' like bitcoin. If you can afford to spare it or loose it, then go ahead.
And you certainly dont want to get involved in the latest shitcoin IPO, thats for certain.
