I accept only Monero donations as they are the most practical ones if you compare them with Bitcoin. With all due respect to all people who are fans of Bitcoin, my opinion is that its initial purpose which was to be decentralized has been put out of the question.
I'm saying this because it's not practical anymore to send BTC unless huge amounts are used, the blocksize is still 1MB like it was in 2009 and most probably it is kept at this level on purpose. I think this video explains it pretty well, of course technical details are not flawless but info is very accurate, I highly encourage you to look into this matter especially if you own BTC.
