Don't know if you've invested? If you haven't invested then analyze the market yourself and decide which coin might be good to invest in. You may also face losses by investing in someone else's advice and blame him. Investing in altcoins is much riskier than Bitcoin, so you need to take risks when investing in altcoins. However, I prefer MATIC between the two coins, I have invested a small amount in MATIC coins. These two coins have good prospects in future, now you can invest in both coins if you want, invest in whichever coin you like best.
