As an investor, what should I look for in selecting the most ideal exchange platform?
For trader the exchange is not much important thing,because they might not move their funds too often but they need to pick a legit exchange if they are going to convert their fiat into BTC or viceversa.I will say LBC will be better to start with when someone begins since it is more trusted and available in all the countries.
LocalBitcoin exchange is limited and doesn't have much coins to trade for or something incomplete to do in trading. That is only for converting fiat from Bitcoin. Why you did not choose those exchange reputable one, I know there an exchange that most likely traders want, I'm not a trader but I know which are exchanges good to trade for. To avoid problems near in the future, pick exchange as a reputed one.
