Before continuing with investment actions in Bitcoin, knowing more details about the storage wallet must be a priority. The Bitcoin wallet is the most sacred place in investing in Bitcoin because assets can be lost if you ignore knowledge about the wallet.
When knowledge about storage wallets is well and correctly understood, then learning to know about Bitcoin investment and all these questions can be done over time as long as you have the time to do it.

Generally, the answer we often hear is buy when prices are low and sell when prices are high.
For me, long-term Bitcoin investment can be recommended. Investments in Bitcoin can be done regularly using the DCA method.
