I did not think that the coin would fall below 3.80. I think that the race for bitcoin made such a failure. I think that it is necessary to sell now and buy cheaper later.
I couldn't sell IOTA if I wanted to - it would probably get stuck in the middle of me trying to transfer it back to the exchange.. either way I'm holding on to it as long as the IOTA foundation doesn't decide to abandon it and run - it is the absolute best coin "on paper" as of today.
