@mammasitta sorry to hear for the lost of return opportunity.

Just to add on top, what being said about centralized exchange. They are free to manipulate the buy and sell of trades. Love it or hate it, we still depend on them buy some position in the currency we believe in.

That being said, I believe many of us here also have similar frustration of being opposite of where you are. Aren't able to get into position during correction. Thus, missing out on the opportunity on the uptrend.
