The altcoin market is extremely crowded right now. It's so risky that most will call it gambling. I only invest in bitcoin, uraniumcoin and ethereum
The altcoin market is crowded because it only costs $25-$50 to get a certain coin created. They are calling themselves developers while they don't know anything about coding. Only a very few altcoins have real developers on board. The other 99% is nothing more than a joke.
Its good to start trading, especially now, because you can make a lot of profit with it and that will be very good.
Because Bitcoin will be more used later in the future and you can also see that the halving is coming and the price is rising slowly.
