Here is a little crypto advice for all that has been said before, but needs reiterated from time to time. Always Do Your Own Research (DYOR) and don't blindly follow anyone.
This space is full of folks who will use whatever means to manipulate people. Not everyone is like this, but sometimes it is people you even know or respect. It is best to watch for patterns and see how suggestions pan out sometimes.
Tips are just that, tips. Technical Analysis is a great tool, but also is not always correct. Charts lie in crypto.
Fundamentals do sometimes as well. As the marketcap grows in crypto, it will be harder to manipulate but currently it is very easy to manipulate these markets.
Know which investments are high risk and what is less risky. Pay attention to your investment choices.
Limit your exposure to what you can afford to lose. Only hold as many different coins/tokens as you can keep up with. Don't buy into things that are already way up.
Lastly, learn from your mistakes. Even seasoned Vets make mistakes. It isn't 100% win all the time. Take you loses as the cost of learning.
