Yes, Eric and Don Jr. have surely taken their footing in a Pro Crypto stance and they are leveraging the inflence they have from the Trump Organization along with the influence of their father to propel new businesses such as the Crypto Liberty Capital or whatever the name of their new crypto exchange is. The Trump family has surely taken their liking to crypto and have used it to further their wealth and status in the world. Its an investment tool for them and even has been a political instrument as well.
They are business people, thus, it is no doubt, they have such kind of move as crypto's influence is further increasing especially for the younger generation. They will use their influence for the benefit of their new crypto exchange. Traders should however be very careful in using any exchange as the mantra says "not your keys, not your coins."
Even we say, that exchange is owned by a known personality or politician. It doesn't stop them to do some routes that can jeopardize their customer's money.
