Most people claiming to understand the technology clearly have little grasp of its wider implications.
Its honestly a bit tiresome to reply to people who say, after 12 years consistent value increase, and a trillion-dollar market cap that its somehow a useless ponzi.
If it is, it's the most successful and self-sustaining ever, and for that alone could well deserve merit even ignoring anything else...
Edit to add: [0] - Warren Buffet first expressed negative sentiment on Bitcoin in March 2014 (https://coindesk.com/warren-buffet-bitcoin-currency ). The price in March 2014 was ~$550. Assuming a 5% portfolio position in Bitcoin held until now, equates to a 4x overwhelm of the entire portfolio at the time of entry (an 80x increase in value of the Bitcoin portion).
