Crypto can be interpreted very generally because there are so many types with different names. Calling Bitcoin a crypto is not correct in many ways because there is only one Bitcoin which is abbreviated as BTC, not WBTC, BCH and others that I don't know about.

If Bitcoin is referred to as crypto, it is not surprising that some people equate all types of crypto in the crypto space as the same. If one of the cryptos is invested and the person is deceived, then Bitcoin will be included in that section. Obviously that is not true because Bitcoin (BTC) is not a scam coin.
