Sup nerds.
I have my 401k with my employer with 5% match and then they match my investment which is neat, have had a Roth IRA that I maxed out last year and am already getting close to maxing it out this year. Any other investments I should be worried about on my radar as a single 26 yo male? With my job I cannot sports bet so that's nice so looking to put my money into something worthwhile. I also have a high yield savings that I put my bitcoin money into but have been told to maybe put that into a mutual fund...
Thoughts? 
taxable investments are underrated imo. good job on the tax advantaged stuff. if you don't have a brokerage account you should open one (can do it the same place you have your 401k/IRA) and like SF said a simple S&P fund (I use VOO) is a good option to set and forget. Also just keeping a chunk in money markets there isn't a bad deal as you'll probably scrape 5% from that at the moment. if you have kids (OR EVEN IF YOU DON'T BUT WILL SOON) you could start a 529 for them. lots of good options out there.
I second basically all of this.
It's currently pretty easy to open high interest savings account and get 4-5%. That's a (basically) risk free way to save for a house.
529s are very powerful if you start early. If you're sure you are going to have/adopt at least one kid even a few years from now (I think; consult your tax attorney) then you can open an account and even just put like $20-$100/month into it. Future (and little) Greg will thank you.
Look into whether you have investment options through your HSA. HSAs are the only accounts that you pay into tax free, grow tax free, and you can withdraw tax free. The only catch is that to you have to use the funds for health expenses. But lucky you, you live in America and our health care (especially for elders) is ridiculously expensive so you won't have trouble spending it.
