I am wondering if I wanted to help advance a cryptocurrency agenda would it be better to donate at least some to businesses that are crypto lobbyists or pro-Bitcoin sites versus just buying and holding crypto?
If so, what would be some such businesses?
Good friend. Since you are new, at least to the forum, it is not surprising that you would raise that question. The answer is no. Absolutely no.
The most important thing to remember is the decentralized nature of Bitcoin.
Rest assured that there is already plenty of money in the Bitcoin world, if you see any pro-bitcoin site asking you for money to promote it, it's a scam. Do not give them a satoshi.
Bitcoin has triumphed and will continue to do so because of its intrinsic properties, and today there are already many institutions involved in it and many people with money, so you can rest assured that without you doing anything Bitcoin will be used more and more, and the price will continue to grow (also in part by the devaluation of fiat, but this would be a topic for another thread).
