Would there be enough money in the exchanges? Would bitcoin fail?
Supply is over loaded and price will fall deeper and deeper. If this happens to Bitcoin the whole market crashes like domino effect. It is different story if it happens to just one or two of alt coins.
Not good strategy to sell your bitcoin to increase the level graph of supply as compare to the demand, it causes decrease in price, but more of the time high level traders do this intentionally because they want to see bitcoin market down which will give them opportunity to buy bitcoin for trading at very low price, then again the buy more than their sold bitcoin to save for long time, so all the time if you see bitcoin market down try to trade at that time and choose long time trading not short time trading.
