Until recently, and before knowing this place I always thought that anything trading or business online is a fraud.
Your post shows the resolve to learn about bitcoin and all around it and this platform is going to help you do that in the long run but don't throw your guards away to embrace everyone and everything online to be true and genuine in whatever is said to you. Many people may yet approach you for investment but be wise and ask questions.
On your own part, there are things you need to do to secure your financial investment like you don't have to compromise your wallet address, keep every password away from third party. Bitcoin is a decentralised digital currency and so you don't need third parties interference. Don't oblige email messages requiring your response or reply when you don't know the sender or not expecting any email.
