Personally I research watch reviews good and bad then whitepaper then decide myself.
What you must always do, always research and consulting your financial adviser if needed and then decide on your own, always invest on what you're prepared to lose.
Welcome to cryptospace.
Never listen to sweet words by people telling you its 100% safe to invest and you will not lose. if you heard this.... you are going to be on their downline for referral for them then they make millions while you lose thousands. So never listen to anyone but yourself.
