The Trump situation is seriously funny. It does really seem like he just wanted to prove a point and now he has no real motives to do anything. Well, we will see how it plays out.
I think it's always important to do your research before investing into a crypto. You must learn about the potential it has to rise. We can't always win trades, but we can always HODL and wait until the prices go back up when they drop:) It's the perfect time to get into new cryptos when markets go down like yesterday.
