Bitcoin might seem expensive, but do you know you can just buy 0.1 Bitcoin for instance?

I personally only advise people to put money into Bitcoin and Ethereum. There are some other Defi projects that are interesting, but I don't know enough about them to be able to give any advise on them. Also don't just buy Ethereum only. In my opinion, any crypto portfolio should have Bitcoin in it.

With every year that passes it becomes way less likely that Bitcoin will be overtaken by any other coin. Bitcoin has been around the longest and has a very safe and simple base layer with a very small attack surface. This means the Bitcoin blockchain is the most robust, safe and proven blockchain available. Add to that the network effect of Bitcoin (it has the largest ecosystem and most developers working within that ecosystem) and it becomes clear that Bitcoin is the real powerhouse in the blockchain space and that it's going nowhere.

With all the cycles that Bitcoin has gone through it has become clear time and time again that the entire crypto market follows Bitcoin. There are some temporary exceptions here and there, but in the long-run it's always Bitcoin that determines how the crypto market moves. All coins follow Bitcoin's lead. That's why I would always invest in Bitcoin when buying crypto.

If you're looking to have some fun with crypto and gamble on a single crypto rising really fast, than I don't have any specific tips. One tip I do have is this: New coins can temporarily rise to great highs when the developers make sure there is a tremendous amount of coins available from the beginning (pre-mined). If a new coin has 500 billion coins issued (Bitcoin has a cap of only 21 million) then any price movement of a single coin will cause an exaggerated effect when it comes to total market cap. And when the total market cap is high, the new coin will move up in the coinmarketcap list into the top 20 for instance and that's when people will really start to pay attention to a new coin. Not because of it's great programming, but because of the huge price move and the "cheap" price of a single coin.

So if you are going to bet and try to make some money, choose coins with a ridiculously large pre-mined supply. A good example from a few months ago was the Shibu Inu coin. It offers nothing new, it's just a meme coin. But because the pre-mined supply is 549,063,278,876,302 SHIB, and the price per coin is only $0.00003056, it still appears as a top 20 coin and that alone is enough reason for many people to buy it.

So if you're just looking to make some money, try to find the next Shiba Inu and dump your holdings when the price has gone up substantially :)
