For me that 2 coin really have good potential. Maybe i can called fan of this 2 coins. But it is better than i talk about tokens that i actually don't where the price will go. That is why i only pick top coinmarketcap coins.
For safe and reliable choices, those two coins are very appropriate options. BTC is always the parent of all Crypto, while ETH is the second highest coin which is very much used their platform by the project developers. Of course both have a high volume and have a more trusted future.
Right, it is good to make investment to coin that already trusted. Although even Bitcoin and Ethereum have possibility to rekt, but it is not bigger as speculate in new coin or maybe tokens that not listed in a lot of exchanges yet.
