I will not advice newbies to trade until they know what they are doing. There is a high chance to loose it all if you are trading without a plan. Best thing to do is to buy and hold patiently.
maybe they can learn something about trading so they can start to trade. it is not a problem if they don't have a big balance for their first time because they still have much time to learn and make a big profit. they can try to analyze one coin and then they can buy a small amount to test their skills don't go all in because it is too risky even for pro trader. try to buy one or three coins and wait for a while and if the price increase then they can start to sell to make a profit.
