Several issues:
1 "Average" vs "Medium;"
2. Assuming many bought high, & liquidated on sell-off, they are no longer included in survey, so as typical on Wall Street stats, major bias. Like changing DOW, etc., by eliminating losing stocks.

4. As most surveys, the major issues averted: Purpose of cryptos? Success in use category? etc.
