If you think Btc is too risky then Alts will be much riskier than Btc. In the crypto market, Btc is King and it is the safest right now. However, because it is safe, the return will not be as high as investing in a few coins/tokens. Anyway Btc is a good investment, I will recommend you some other good coins:
- Matic
- ETH
- LTC
- Sol
- Uni
- Link
