If only you're really in a group that has some good signals and strong on what they promote but if you're into group that just promote a pump and dump coins/tokens expect the worst case scenario.
Most cases, the group only does pump and dump, trying to find a genuine group among the ones running in social media is a waste of time. It is better to develop your own charts and process your own predictions and try in on paper.
Joining an ICO isn't bad if you can afford to lose it and always expect that there's risk involve in it much higher risks compare if you invest on projects that are already in the market.
These days, ICOs have become rarer and it is more IEO or IDO. The risk is almost 100% currently with the projects ending up as failures or scams. I find this money worth spent if we buy bitcoin than any new shitcoin. At least with bitcoin, there is no chance of developers abandoning the project or getting delisted from major exchanges.
Newbies should not try getting into ICOs with their money just because bitcoin is pretty high prices compared to their capital. Buy fractional amounts regularly when the bear market starts, till then keep patience. One day after launch of a shitcoin project, the market is messed up. It becomes a shitshow and trying to get into the coin at that time, the only loser will be the investor.
