Instead of choosing one, it is very good to invest in both these coins in the market because the potential it has will always benefit us in the market. If you look for a short term you won't get much benefit from these two coins. It is always good to accumulate when their prices are low in the market and it will help you to make a decent profit if you manage your patients.
It will be even better to add to these two cryptocurrencies some altcoins that are the best-trusted ones. I am talking about Litecoin, Monero, DASH, Zcash, TRON, and Cardano. You need to hold at least 7-8 cryptos.
