I would take that money and burn them on the streets instead of buying any of those useless coins. No offense, but they both are useless and they do not contribute nothing to the community in here.
Why do you say so? Cardano and Bitcoin Diamond are not shitcoins, in fact they have value and it is good to invest with these 2 coins. If I will choose between this 2 coins, I prefer to choose BCD than ADA, why? Because most of here wanted ADA and I want to defend BCD because it is a fork of bitcoin. Meaning to say, it also good as bitcoin and I think there BCD is more ambitious than ADA so there is a possibility that its coin will be like as Bitcoin Cash, who want to replace bitcoin.
