Honestly you must be very stupid to sell at that level...... at 100 or 150 I would understand yes because that would be a reasonable price for this coin. It just needs some more promotion, good looking material etc as the work these guys provide is already pretty good. I stick to the target 100 USD for now. Look at the market cap and rank.....this coin is unknown and in stealth mode.
