##NFT Drop - Best Practices 

Every successful NFT projects start with a great idea, great artists, an amazing team, and a dedicated, enthused community.
But one aspect that most NFT projects tend to neglect is the minting process.

As someone participating in a dozen drops weekly, I often witness NFT drops that end up with the majority of the faithful community members wasting hundreds of dollars (or thousands) on gas, being front-run by bots (like mine), and with a distribution of the supply being lower than 30% ownership.
If you have 50K discord members, and a 10K supply, even team should aim for a distribution as close to 100% ownership as possible.

Building a successful NFT drop is difficult; You have to think like those bots, think one or two steps ahead and lay traps for them.

1) go to https://ropsten.etherscan.io/verifyContract?a=0xa32b21ba14fd476757e392db5d1bbc833eaedaf5
2) enter contract address, name, compiler
3) copy code of contract flatten out (delete import and replace by actual code)
4) truffle console
5) var Eth = require('ethjs')
6) Eth.abi.encodeParams(["uint256", "uint256", "uint256", "address", "uint256"], ["1508105298", "1508710098", "200", "0x3d208fabaf7e919985d5d2f068f28d6a9022e8d5", "5000000000000000000000000000"])
7) copy paste result of encodeParams without '0x'
