@Rutgers Chris as well.
In my opinion, now is still a perfectly good time to start DCA'ing into BTC. I wouldn't create your entire position since it is close to all-time highs and as a volatile asset better prices are very likely. Perhaps get a little skin in the game now and see how you like it. Buy more during the next dip. Rinse and repeat.
Different ways to buy:
1. BTC ETFs - IBIT or FBTC. Most simple way to get exposure. I have a FBTC position in one of my rollover IRAs.
2. Fidelity Crypto - Here you buy the coin directly, but Fidelity holds it so you don't have to take custody. I completely trust Fidelity as a long-time customer. My entire BTC coin position is here.
3. Coinbase - Buy BTC directly and use their Wallet to take personal custody.
