I am currently thinking about investing a larger amount > $20k which I have recently received through sales of some shitcoins that I don't think have much of a future ahead of them. I have already done some research myself. But for the final assessment I would like to hear your opinion. Which of these following projects do you see as a great investment and why?

• Cardano (ADA)
• Polkadot (DOT)
• Avalanche(AVAX)
• Litecoin (LTC)
• Cosmos (ATOM)
• IOTA (MIOTA)

I have already severely limited the number of possible coins. The original list was around 30 coins, but after the research, the above six coins remained. Therefore please do not name others.
