Seems that every Wall Street are into bitcoin right now, they smell huge profit to be made as we have started a bull run already and perhaps they don't want to be left out in the closet when we have a massive run thru 2021 and beyond.
Not surprised, a fund like this gives their clients a solid hedge against a falling US dollar (and with more upside than gold). This will probably introduce younger clients to Fidelity's services too. Once their crypto fund see's some green, they'll probably invest more in the firms other services.
But it seems that it is not for everyone though, $100k is too much for average Joe traders, so I guess this is really design for bitcoin whales or retailers who have huge money to invest in crypto at this time. If we are in a bull run definitely crypto fund are going to see green and probably will attract more and I'm sure that there will be businesses or companies jumping on the bandwagon and offering similar services.
