Hello guys, I'm new to bitcoin, so there are things that I misunderstand.
I have a big interest in bitcoin, in the future, I want to make money with and invest in bitcoin. So I really need your advice.
1) Which wallet should I choose to keep btc? There are so many choices so that confuse me. I know about Electrum, Blockchain, Coinbase,... Does it secure?
2) I need to make money by myself before I invest them, so how can I do to make some bitcoin?
Thanks for your help.

All of the online wallets that you have mentioned are all secure, and as a newbie, and for you to be so sure that your bitcoin would not go somewhere else and safe, I suggest you to use blockchain. Many of the bitcoin users here use that online wallet, since that is the bitcoiners choice when it comes on storing their bitcoin.
My opinion about using blockchain is a lot more better because since there are so many bitcoin users that are storing their bitcoin there, then even there would be a consequence that all of the bitcoin their have been hacked, then, it's okay, because it is not only you who lost bitcoin, but also other bitcoin users, so in this way, you can easily move on, well, it is just a point of view to explain why blockchain is more safe than other online bitcoin wallet.
