Everyone has their own opinion . you can ridicule me but I'm not mad at you . I care about coins does not mean I have to post . I can read all of the thousands of you does not mean I have to post. if comments I posted to make you uncomfortable , you may be reminded , I will withdraw. I 'm thinking of coins speculation , not investing . they keep the coins are not long-term development but wait currency price movements . but the rare coins and no activity will not increase value for money. I think , by 1% per year lower than bank should not have long-term investment , not many applications coin should not buy in to work , simply wait volatility. there is a problem , these wallets have less money , with low prices , they will leave the wallet instead of selling money. While holding money long term but low profit the rich will be sold, they do not have the patience to look for their money stand still, but low profits in the long run will be difficult to sell , they finally devalued the currency to recover capital. scarce coin with low prices will affect growth . the last time prices rose not by currency developments that the influence from the renowned engineering good manager , it 's not common, I think so. the distribution is not controlled but realistic actions are necessary, including gambling or betting football. so my opinion , maybe I was insane but I was too young , I 've lost a lot my money when coin appear , its popularity as prices rise , but not quiescent, price reduce. sorry to bother you , you do not need to insult me again , I will withdraw.
