None is safe, all is risky.
If you are going to pick the safe investment, you would better choose investment offline like in a property.
But here in crypto, none is safe. But this is interesting because we can take profits multiple times only in a short time, different with offline investment.
And about long-term investment, just pick the top coins, not new coins with hype, it will decrease the risks.
I will prefer to choose BTC, ETH, BNB, and also other top coins
