Success is not promised even after doing the work but what will you gain if you don't do it?

if you don't risk anything you won't gain anything, you might not win the first time or receive any income at the first try but it doesn't mean you won't gain anything.

You would gain knowledge if you loose but now after that lost it would be easy to win cause you already know what went wrong the last time and now you can analyze and prepare your next steps.

$BTC wont guarantee you success and an income but it also doesn't guarantee you would be at lost.
