Your right it is frustrating at times when you see the price dropping and you try to take some profits out or see a dip and try to buy in, when there’s a mad rush in or out it overwhelms the system. Normally everything works smoothly , but when bitcoin, or litecoin starts shooting up to new highs,might not be the best time to get in.
But I feel your frustrations, took me a while to get coinbase after chasing the rest asking for all kinds of verification such a s Gemini , but again coinbase worked out.
