Sure! Though I'd say just about any currency is fine to get started with. Keep in mind that you don't have to purchase an entire unit of a given currency - one Bitcoin may be $40k, but you can still just buy $10 worth (just be cautious of transfer fees, both withdrawing from exchanges and sending from your own wallet).

I'd recommend also looking at ETH (using MetaMask as an in-browser wallet to interact directly with websites is pretty cool) and XMR (dirt cheap transfers and your financial privacy is safe).

its a memecoin

LTC i would says is a good coin for that.

Why would you recommend it over Doge?

Does that mean phony?

Just make sure that whatever cryptocurrency you buy, can be traded in exchanges otherwise you will never be able to cash it out.

You are wise wanting to experiment with it without risking any real money, cryptocurrencies are highly instable and impossible to predict, treat it like a lottery, you can get lucky, not because you are smart, but because it´s luck, and more often than not, you will lose everything.
