Crypto plunge has not dented owners’ investment optimism. Here’s why.

• Cryptocurrency markets have plunged and Coinbase's CEO has warned a "crypto winter" may be ahead.
• But crypto users aren't deterred, a Morning Consult survey shows.
• In fact, the share of respondents considering buying more has remained nearly steady all year.

Cryptocurrency enthusiasts have remained resilient even as the cryptocurrency market has crashed and burned this year. 

Bitcoin last traded around $20,000, less than a third of its all-time high near $69,000 reached last November, while other digital assets like TerraUSD are near worthless and crypto lenders like Celsius Network come perilously close to bankruptcy.
