Follow a lot of crypto- and fintech-related twitter handles, so that you get a lot of varying news. When something news-worthy regarding an altcoin hits, jump on coinmarketcap, find the coin, go to the Markets tab, and look for big discrepancies between pairs on varying exchanges. Clean up.
I'm looking at one right now that I can buy for $1.78 and sell for $2.00. Buy $1,000 worth, and cash out $220, minus your fees.
I use the standard blockchain.info wallet for day to day. Ledger for safekeeping. I have accounts at many exchanges. Just pass the KYC, do your trades. I keep funded at many exchanges, to take advantage of the trades. I transfer back to my wallet once profit reaches a certain level, leaving enough in the exchange to do more arbs.
