It does not matter how long, or how many years you are patient and learn how to trade, the possibility of making consistent profit is wholly slim, and can even be said to be improbable, trading is somewhat risky business, and it does not matter how much knowledge you have, you can lose a lot of money in a very short time, and you making profits consistently is never guaranteed or even feasible.

I would just advise people to be themselves, do not jump into things cause of either FUD or FOMO, there is quite a lot of thing you should even know about Bitcoin before either speculating or trading, people take all of these for granted, you can't jump the process and not expect to run into problems sooner rather than later. It is also important that as you talk to people about Bitcoin, you do your very best to also tell them that it is money/currency, and can be used for making purchases.
