I am in favor of more crypto investing options at Fidelity. It diversifies my portfolio to reduce my risk. BTC was a good start as an approved ETF. I personally have purchased FBTC from Fidelity. Unfortunately, the power required to process BTC blockchain (using proof of work/POW) is alarming. ETH however uses 99% less power (proof of stake/POS). This is the future. Have BTC alone is ok. Adding an ETH product, would further diversify my overall risk.
