Yes to the first question. Maybe to the second.
Decentraland, Sanbox and Axie Infinity are the current top three players in the metaverse space. They might be the safest bets today but this space changes by the hour and what's in the top 5 today may not be 3 months from now. I am fairly sure they are on Crypto com's and Gemini's exchange. Dencentraland and Axie are on Coinbase. KU Coin and Binance.US are also places to look. I prefer CoinGecko's listing of the various metaverse projects:

You can use
CoinGecko and
CoinMarketCap to look up individual projects and get a feel for them and where to purchase down at the bottom of the page. Both should have a Cliff's Notes version of what something is trying to do and links to their sites, whitepapers, social media, etc.
Beyond those top players, you're likely headed off to MetaMask, Trust Wallet, etc with BNB (Binance Coin) or ETH in hand and then off to Pancake Swap or Uniswap to swap coins.
The second question is swim at your own risk.
Vegas posted EGC (EverGrow Coin) among a couple others back on page one. I took a look at EGC and RMTX (going to their sites, etc, getting a feel for things) based on Vegas' suggestion before putting a little in. And by a little, I mean around 1-2% of what I have in crypto that if it goes up in flames in the next hour, it stinks, but it's not the end of the world. EGC could be something but honestly it's just potential right now. RMTX's success will likely be tied to EGC's success.
This leads to the question of distribution. On another forum I frequent, someone who has been in the space since at least 2015 suggests 90% BTC/ETH, 5% in other major plays of your choice (Cardano, Solana, Polkadot, Chainlink, etc) and 5% high risk plays, aka, ####coins. Me personally, I'm around 84 / 14 / 2.
Grayscale's large cap crypto holding breakdown more or less is currently: 60% BTC, 30% ETH, 3% Solana, 3% Cardano, 1% Uniswap, 1% Chainlink, 1% Litecoin, 1% Bitcoin Cash.
