I have a question regarding the morality of buying these coins: 1. In buying I provide liquidity and add to the perception they have value. 2. I am aware they are a big Ponzi scheme and vulnerable people may lose money they cannot afford to. 3. However altcoins may be a "too big to fail" Ponzi scheme, which like the property market, will rise seemingly forever. 4. I would rather be on the inside than the outside if it does. I'm on the outside of the property market in the UK after correctly assessing it was a pyramid, but wrongly believing it would crash and not be propped up. 5. Good and vulnerable people might lose their savings because I have enabled a perception that these markets are not pyramid schemes.

Please advise.
