The only way to get past this just like in stock markets is volume. If there isn't volume it is easily manipulated by these bots.

With volume, bots have a hard time keeping up and adjusting to all of the action which sometimes ends up with the person controlling the bots to actually lose money/value because the bots are not fast enough.

You can sometimes fight the bots by doing small transactions.

I think the problem with alt-coins is that there are just way to many. Like everyone and their grandma has created an alt-coin. It really gives the crypto currency a bad name, and it takes attention away from real game changers, real alt-coins looking to revolutionize currency and transactions. Exchanges/Markets need to stop accepting everything and maybe have some sort of qualifications to get listed. Qualifications like proof of concept and real world application of the coin, etc.
