I scraped together the little money I have and dove into bitcoin. My ambition is to make money trading altcoins and keep a bitcoin reserve. Can I even make it anywhere starting with such a small amount of money?
Yes you can start trading with 25$! the real question, are you willing to lost your investment? without proper knowledge, your 25$ will be gone quickly.
You can buy few altcoin with that amount, don't worry the quantity or portion which your going to buy will still remain, even the price are going to drop.
On my first trial with trading, because of my fear and lack of knowledge, I lost almost 100 dollar.
Learn basic knowledge before jump on trading.
