snipertech.py

# You'll need to pip install web3 for this, everything else should come as standard

# Works as 'python snipertech.py {target-casesensitive} {sharesToBuy-1_to_9} {maximum_total_amount_in_ETH}
# e.g. python snipertech.py functi0nZer0 1 0.4

# Loops in ten second increments to try and buy your shares if they don't exist on FriendTech yet, then crashes out
# Adjust loop length on line 86 if you want to be less frequent - if they already exist, it just buys and dies.
