There are so many coins in the market and new ones keep coming which we need to understand that we can always buy and hold to try to earn some profits from them. Selecting a particular good coin from random of bad or scam coin can be very difficulty and we need to be wise when making decisions about what coin to buy and what coin not to buy. We can always make money from buying good coins but the problems comes in when we don't know how to identify good coins in the market. If we still want to make money then we have to be prepared to join coins or community that would keep updating us on recent new tokens to buy.
Of course calculations are needed here, especially this is about how to find additional profits from what we invest in the coin. Many who just choose to reap losses and buy them carelessly following the hype for a moment and the funny thing is that it again enters when the price peaks.
For the community, of course, it is necessary and true as you said where there is information about updates needed, especially if there is a good and producing event held by them. But, in the group must be careful there are also many who claim to be admins as well and they are scammers who look for weaknesses from group members if at any time there is a problem that wants to be smoked in the group.
