why USD is so strong ; despite crude fall and so much turmoil inside USA ?
Because it’s USD and way too many people behind it to make it strong, nobody really can get some damage to that currency, but nobody could do it… the only way to make your own economy stronger and then maybe if everyone would do it it will be really sort of fall globally a bit, as you may see all other currencies falling down a lot to that level as well. USA is still leading country on many levels and have huge debt which they are not going to pay anytime soon, so probably all that counts as factors to that topic absolutely. If you are getting USD income - you are lucky guy.
