BE very carefull. Don´t trust anybody, this world is full of laiyers and scammers. Go to Gdax, link your bank account and then you have yoour dollars in Gdax. You can then buy Bitcoin, Ethereum, and bitcoin cash. I recomend you to buy bitcoincash now that coins are cheap, and hold for one or 2 years. Don´t try to trade if you are new, because you are going to loose money then. But if you buy any of the cryptocoins in Gdax and you hold for one or 2 years and don´t enter in panic if it goes down, and stay firm like a rock, then after one year, you are going to have 3 times your money. Be gratefull for it and forget FOMO (fear of missing out), when you see a coin that is raising, because at the very moment that you will go in , it will go down. Follow my advice, and you will earn a lot of money. 3 times your money is the best investment in the world that you can find.
