Bitcoin is one of the most popular and in-demand coins in the cryptocurrency market. Many are investing on this Bitcoin and even many are investing. When Bitcoin was created, the price of this coin was very low and gradually as time passed, the demand and price of this coin increased. I wish that I invest bitcoins but unfortunately I don't have any bitcoins and don't know how to acquire it. Is investing in Bitcoin easy or complicated? Is it possible to achieve success by investing in Bitcoin? The main thing is how one can earn if he invests in Bitcoin and if he stays for a long time.
I’m not sure what you mean by earning but the moment you buy buy a bitcoin or some sats, as soon as bitcoin start to appreciate in price, you will profit from the increased price and you can view it from your wallet. However, if you are implying on how to increases your bitcoin quantity, then that's where staking service comes into play.
I will not recommend staking but we have people that does it and it's profitable for them though I wouldn't run from the truth, staking comes with a lot of risk, like when you stake your btc either in a centralized or decentralized staking service, you can't unstake until the agree date is reach and there may be an emergency where you may want to sell some quantity but because of staking contract, you can't unstake it. There is potential possibilities of the service not running in the future, we have seen instances where many bankrupted and for what exactly? Because of 2-4% APY, it doesn't worth the stress and anxiety.
