Your opinion is correct because the bitcoin market is always volatile. No one in the bitcoin market can say for sure what the future holds. However, before investing and trading Bitcoin, you must have previous experience.
Even you don't have, a newbie cannot gain an experience if he's not going to get in and get an experience. So if it's a requirement for one to invest bitcoin and start trading to have an experience, then, all of us shouldn't be here if we don't have that in the first place.
Well, anyone can trade and invest regardless of the experience but there's the advantage that he gets when he has it. But, he'll only get it through his own involvement in the market.
Experience is really the best teacher and if you won't invest with bitcoin in the beginning, you wouldn't be knowledgeable to invest with other altcoins. Don't underestimate the learnings that you could gain through actual trading no matter how big or small your starting amount is. Bitcoin as the father of all altcoins is too profitable especially if we'll search everything about it including its history.
