Any crypto I have bought. What makes it scary and maybe not such a good investment is also what makes it a good investment, it is extremely volatile. So if you can watch it and play the game a bit there is money to be made rapidly. I think though it is considered “high” right now, we are still in the infancy. There is so much potential and such a long way to go with this.
And my favorite part, as trust in government goes down, the crypto prices go up. Which I feel is only going to continue for the forseeable future seeing how the governments around the world are acting.
