Preposters already gave interesting advices for choosing technical indicators, so I needn't repeat that once more. Additional I suggest you to devide your funds for day trading and longterm trades. Put 90% into longterm trade with deep research. Only put maximum of 10% into day trading with following advantages.
1. Little funds on day trading prevent you from panic sells and give you more freedom in trading.
2. You can make also with very little amounts big profits, when you get it managed to profit 2-7% a day, you can earn theoritcally with an initial investment of only 10$: 353,21$ - 1.945.718,39 $. So the advantage is clear. Independent from your skills you will only loose a little amount with the perspective to gain big profits.
3. You can try out all the recommended indicators and strategies.
4. The most important: There is no indicator, that will show you the future of price movements on day trading with an accuracy of much more than 50%. Interesting in that context is the study by caas business school, City University, London, about monkeys predicting bulls and bears:

Only illegal trading with insider knowledge braught securely big money (Search on google the keywords coinbase - insider - bch)
Longterm trades: When you invest into well established cryptocurrencies and ICOs with serious backgrounds (established companies/services) and hold them on longterm (don't put your whole money into cryptocurrencies), then you will probably gain big profits, because you have the advantage, that prices of cryptocurrencies don't follow prices of traditional markets. We are just at the beginning of a new technology, that has big headwind of governments and banks, who want to keep control over the financial sector, but it is not stoppable (like internet wasn't) and will for my opinion continue to grow, although there are drops from time to time.
I divide my portfolio into three parts 30 for short term and another 30 for midterm and another 40 for long term trading
