How can you profit in BTC if you don’t even invest any money in the first place. That is dumb af and not even worth the effort

Yuph, The best way to earn bitcoin without investing money is by Joining Bounties in this campaign. You can participate social media campaigns like twitter and fb campaign. Hmmm you're still a newbie to join a signature campaign. You must rank up first.

If you want to invest. My best suggestion is by holding your coins until the price gets higher then sell it.

The fisrt step you should create an accound and start se Whinchester charts are good. Do not forget to consider because all the dicisions are in your hands. Buy in the price down and the amount if you think it high, it is the primary key if you want to maka a profit. Good luck!

I think you should invest first before you make a profit. Invest your $10,000 for a long term, as i can see you're new here so it's a little bit risky to do short terms. But you can earn in other way, like joining signature campaigns you can earn just by posting or sharing your knowledge about cryptocurrency here in forum. But you must higher up your rank first because they don't accept newbie to join their campaigns. Just take time to read others posts and after that you will earn some information.
