exchanges are what makes world go around, without them, coins MAID or other would lose majority of their current value.
i think coins on poloniex are more secure then on average user PC that has 1 format per year and 0 backups. there was downtime, people trading lost their money, thats life, because of that unperfect technology they made much more overall then they lost that single day. we shouldnt go back to stone age just to migate risk of electronics breaking down. exchanges move economy, progress the scene, get people involved in trading.
i dont know who is Charlie Shrem and i wouldn't care about his opinion
as for maidsafe coin, i would ask everyone to be little bit less romantic about entire idea, coin has no value whatsover, and will never have any value, other then we agree upon. thats how market works. value is determined by what we agree it is. when you buy 1 loaf of bread in a shop, its value is not 1 euro, it is what we agree, it can be 1 euro 2, 20, what ever we agree it is. people dont understand that price sticker, label, is just a an offer, a proposal, it is something that you can agree with, its not a value of anything in this world. dont think maidsafe network, applications, solutions of business problems have any affect or will have any value that will give value to a coin. in essence coin is not required for maidsafe network to work, it can work without it, and we can pay for it with euro or us dollars. coin was only made so developers can get their salaries.
