If you do not know what Arbitraging is, or even why it is something you might want to look into, then watch my YouTube Videos here: https://www.youtube.com/channel/UCaCdbZMApiTpk_AUOwkLsKw
Arbitrage definition from Encarta dictionary: "the simultaneous buying and selling of the same negotiables or commodities in different markets in order to make an immediate riskless profit"
The minimum investment allowed into aBot is $250. This remains true even after the first deposit into aBot - ALL deposits/investments must meet that minimum.
I recommend you start with an initial buy of at least $300. This will allow you to cover fees , and still leave a bit in your MetaMask wallet, to cover withdrawals or other transfers. I usually leave at least $5 worth of ETH in my MetaMask.
