/* YoBIT Trader Bot v0.9 */

/*

This script performs small buy orders on a select trading pair on YoBIT.

It automatically re-sells the purchases, up enough to clear transaction fees and make a profit.

It keeps track of own sells, so it never purchases from itself.

It recombines sell orders to save on transaction fees.

It can be customized to trade all the way up to a pre-set target.

It will only create small buy orders, up to customizable max BTC value.

It will keep the market active, move the market up, and has proven to be profitable in a group effort.

It allows you to buy manually, off of the YoBIT website. The bot will perform sales for you at a profitable rate.

Has been used on ORLY coin, TCR and POST. The more bots run, the faster increase of value.

WARNING: Default BUY_VALUE has been tested, do not increase too much or you might buy too much to sell.

Enjoy.
