Question: is there any technical analysis or analysis reviews good for the crypto field? Can I rely on these analysis to predict the future trend of crypto and do investment and trading?
They are good, don't doubt in that, they are based on history. Can history be uses for predicting the future, don't relay on that.
Can you invest money in bitcoins today and to make 30% profit in a week? Check technical analysis to see is something like that happened before? You can check technical analysis for possible price movement patterns, and that should be like confirmation for prediction you already have.
When you trade with crypto relay just on yourself and try to have back up plan for every possible situation. Make your prediction on more than one thing, news, technical innovation, big things like selloffs are, check are news are true or false, then check technical side and than make your trades.
