Seriously it took me time before getting on Crypto world. But no late comer. I guess one will think it's all a waste of time before you see it happen. It's all real. Good effort, patience and carefulness matters. Crypt is going global so reliable with good income.
Honestly, your question is a little bit confusing 
but don't worry I get your point. When the moment I entered crypto world doubt never comes into my mind. I admit there are times that I felt hopeless and discouraged like happened to most of us especailly during my beginner days but that's all, no more no less ~ I still do believe in crypto. That is just because it's very upsetting to know that I'm not yet able to earn profits from it (btc to be specific) but everything changed when my first withdrawal already came. I believe stronger and my hunger to earn more suddenly boost up (sounds greedy but it's not, I just feel motivated). This attitude of mine continues until now and try to do the same way too. There are chances that you may be scammed along your way but never lose hope but be better instead.
lol, taste of money isn't innuendo for correct course of action, you should doubt to understand that you are doing right
