Trading takes time to learn it even depend on your brain capacity to truly understand how trading works, it's better to engage in both trading and investing, I have a close friend who do this and use the trading skill to survive pay bills and others then still be able to buy few BTC every week now he is in a better state financially
What has been done with your friend I'm sure it didn't come for granted,
he must have suffered a loss somehow because it was part of the process and until he finally got to this point where he was in good shape financially
