Holding baby, this bull run is just getting started! We got a good 5 months to go before we get anywhere near the top of this run.
The only hesitation I have is how much of the premium over the actual amount of bitcoin in each share will be affected if a true bitcoin etf is approved by the sec. Gbtc does trade at a fraction of what the premiums are on other grayscale holdings but it's generally between 12-30%.
I really don't see how people can afford to risk not having 10% of their portfolio in crypto, specifically gbtc. If I wasn't in now, I would be ready to pounce at the next 10% pullback of btc price.
I'm currently at about 98% in crypto related investments, but I'm also playing with a lifetime of house money so I wouldn't recommend that approach.
