The knowledge to become a successful cryptocurrency trader won't come in few days it need to gain through lot of self learning and dedication over long time period buy there are some tips I have learned throughout my journey that I would like to mentioned such as

1. Invest an amount that you are able to afford and prepared to loose

I have mentioned the above because there are some newbies who goes to the extend of taking loans to invest in Bitcoin or other altcoins which I think as a very bad decision because in nature bitcoin is highly volatile so the risk level is much higher than any other investment asset so it is not brave to take unnecessary risk

2. Make investments through proper analyzing but not based on trend

No matter how significant the trend and the demand level for Bitcoin or any other crypto is do not make decisions based on other investors or traders actions and always do through research and investigation to understand essential facts why the currency is moving up or down

3. Never think you know the market so Continue learning

Most experts tends to loose both there money and time because they get over confidence once they earn some money and they tends to do investments according to there guts but in reality the bitcoin market is unpredictable so the investor should always keep learning to know the market price movements to gain income and avoid losses

Above are  the things I have learned so far from crypto investments
