/*

Snipy AI is an ERC token that works in tandem with a snipe bot to take advantage of short-term price movements in ERC tokens. The bot uses algorithmic trading to make trades quickly, reacting to shifts in markets and aiming to capture profits in a space of seconds or minutes. Snipy AI tracks ERC tokens while looking for the most profitable trades to make. By utilizing the bot, investors can hope to capture and reap greater returns on their ERC token investments.

Snipy AI uses an algorithm to avoid all the possible scam tokens and always takes exit if a developer tries to scam , all you need to give the bot sufficient gas fees. Snipy AI have special feature to Snipe the most hyped up launches for SAI holders.

There are basically two methods to Snipe in Snipy AI:

1) Manual mode which completely supports windows as well as mac where you can set all your desired settings.

2) Automatic Snipe mode where you can set the bot to get desired Xs and it will keep searching the most hyped up launches to Snipe them the first.
