Create your checklist of what you want to achieved in the Bitcoin market, most people will just jump to any site you're introduced to and buy coins after a while you discovered you cannot have access to the site's. Many have lost their wallet for careless and impatient to learn, when someone introduce something to you, first of all do a proper research of that site, learn what the site is all about.
Site? Bitcoin funds are not meant to be stored in any website, you are to buy your Bitcoins from an exchange and send it to your own personal wallet, it is only if you leave your Bitcoin funds in the exchange that you can quickly lose access to your funds. Do not allow just anyone to recommend you where you should buy your Bitcoin, you might download a scam or clone wallet and lose your funds, always do your research on the best crypto wallets to use, and make sure you download it through the official website.
Try not to rush investing your resources first check your list of interest, ask questions and follow your mentor amicable, don't try to be too smart to outsmart he or she.
Mind you that you should not depend on any mentor/expert to give you advice on what you should invest in, in this network you have to do things yourself through research, if you allow people to babysit you, you'd prolly struggle to learn and could lose your funds. Remember: "do not trust, but verify".
