Wallets are a good example of this. Many cryptocurrency storage solutions — for example, hardware wallets like the Trezor and Ledger — are designed with maximum security in mind (with good reason!). But these aren’t meant to be used with day trading: the amount of time it takes to sign and confirm transactions from wallets can delay trades that you’re trying to perfectly time.
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
