I only take one note: Don't be dazzled by the "profit stacking" of re-pledging/sharing security. First, keep the exact time and amount of every transfer, currency exchange, pledge in/out, and reward arrival (save screenshots + export CSV + on-chain links together). Otherwise, when you file your taxes at the end of the year, you'll find that the hardest part isn't calculating profit or loss, but simply remembering what you actually did.
