I wouldn't buy GBTC at 1750 per coin, but I could do 380 and 420 like some have. By the time I would cash out some of my 401k and get taxed and penalized I would end up spending more than that per BTC, so to be able to roll a bunch of my 401k into bitcoin is well worth the added cost of each share. I am planning on buying GBTC shares with 10% of my incoming 401k contributions once the ask side is built up. For every $1 I put into my 401k my company contributes $2, so I am very excited about this.
