The way I see it, 90+% of the price of Bitcoin might be speculation, scams, black market, whatever you dislike the most. The rest is honest value for the only robust asset that can be exchanged across any border and is not subject to the whims of governments and bureaucrats. It is the "digital currency for the Internet age" Milton Friedman was describing in 1999.
(Insert 50 pages long disclaimer here for the HN pedants wanting to point out it's all a scam, that it's not a currency, that it is actually subject to the whims of governments, that it has no value, that it boils the oceans, that it is not the only cryptocurrency, etc.)
Yeah, I have the same issue - I cannot use Paypal nor IBAN to donate to KDE, but I have money in crypto that I could've donated them, but I literally cannot. Too bad the German laws are set up this way (https://kde.org/community/donations/others/ - "KDE e.V. does not accept donations of "crypto" coins: Bitcoin, Etherium, Litecoin, Dogecoin, and all the others. The tax regime that covers German non-profit associations considers those coins a form of speculation which would endanger our non-profit status, so regretfully you cannot donate them directly. Cash out and then use a traditional method to donate.")
