Short term investment and long term investment is better if you immediately try coins like Ethereum, Binance Coin and Polygon (MATIC). In the last few weeks, Polygon has been moving really well and I think it's worth studying. However, if you want to also try investing in NFT, try studying ENJIN or TEZOS.
I think the three coins are more appropriate for long-term investments, it seems more profitable,
there really is no doubt that the top altcoins have strong fundamentals and this is suitable for the long term,
We'll see what developments will be next year
