If yes, what are the best strategies? Bitcoin is so volatile now.
But yes, there's nothing wrong if you will use technical analysis in trading Bitcoin as your preference. However, if you're a long-time holder technical analysis isn't necessary because it is based on fundamental analyses that are monitoring some trending news on Bitcoin that could affect the price quickly on the market.
If you mean trading on Bitcoin and Altcoins on the crypto exchange platform, technical and along fundamental analysis are much more important.
Both are very important to have at least a reference on how to predict the market price.
