You cannot set too many buy orders, the exchange wont let you.. You can only set up buy orders equal to the amount of money you have availible.. and these are high percentage trades, so if you have $1,000 dollars, i would split that up, into atleast 3 parts.. $330 $330 $340 and then trade three different low volume coins.. even if you make 20-30% on a trade = lets say $100 profit per trade, that only takes you 10 trades or so before you have doubled your account.. but you have alot less risk than putting all 1,000 on the line in one trade.. 10 trades go by fast, maybe 2 weeks and you will double your account.. thats how powerful this type of trading can be on a small account
