Luckily never had to deal with Kraken
Kraken and Poloniex are GARBAGE exchanges. Kraken had problems in the past with payouts and also screwed people over when marginal trading went down the gutter a few years back. Polo's support is HORRIBLE. But 90% of exchanges suck.
You have very bad experience i think about exchanger because you said that 90% suck.
However although we can not believe any exchange but we still need to use 1 of them to trade.
Agree. Although competition leads to innovation, with such little overseas regulation, it makes it tough to weed through the "scam" exchanges.
