Good work!!

@chibie be sure to update your branch with master and check travis failing before merging it.
As a general rule as now travis is back again we merge branchs when travis is green unless the error is not from your code (like now)

@aamustapha / @chibie could you tell me what to add to the Token Table
Decimals + token symbol + chain id etc etc
I'll add it in

[amustapha]

Chain_id is 56

Token symbol
BNB and BUSD.

Conversion

• 1 BNB -> 29 USDT (as at last I worked on it)
• 1 BUSD -> 1 USDT
