Buddy if you want to invest in that size you should be the one or personally doing a little researched about the coin/token before you invest your 10K Euro, since if you continue listening to other peoples opinion or suggestion i'm sure they will give you also the coins/tokens that they are holding. in that case your opportunity to choose a promising coin/token base in your own knowledge and judgement will be discarded and that's not good because if ever the investment has become failure i'm sure blaming of each other will be follow and that's quite annoying.
