I only know bitcoin and Ethereum. I want to know where you get the new coin information and how to judge it as a good coin.
While it might be tempting to buy altcoins because they are cheaper, or because they are perceived to be cheaper by the market, this isn't the best approach. Make sure that you have a balance between more established and more mature coins in your portfolio.
For newbies its not advisable to buy new altcoins since they don't know how to diversify their portfolio yet and they are prone to get hype by their supporters that's why its really better to split up their investment on different coin at the top and do spot trades since most of the coins there have big potential and low risk since we now even if the price dump the chance to get up is high. That's why never follow to buy cheap or low cap coins since this is risky type of option what others do.
