You right man, we better not to engage anything if we don't have enough knowledge especially in crypto. This is the reason why a lot of people loss their money in just a single twink. We must study it first before taking a step inside.
That is why there's a lot of those newbies who fall prey to those pump and dump groups who provides signals for a fee. Instead of making their own research on what coin to buy, what token to put their money in, they just sign up to those group and wait for a signal. It may be hard to trade at this moment because the price of BTC keeps on sliding down but there are alts out there that are still good to buy and are at a price that is too low compared to what they are suppose to their market value.
