How many ways to gain #BTC ???

Through Minning:

When Bitcoin transactions are completed—and a new block is added to the blockchain—a Bitcoin is ‘minted’ in a process known as mining.

The process of validating a transaction is complex, and requires computers in the Bitcoin network to solve a cryptographic problem. The first to do so is rewarded with the newly minted Bitcoin. By this process, around 900 Bitcoins are ‘mined’ every day.

Lending Bitcoin:

Bitcoin lending is a popular method of earning Bitcoin.

Some centralised exchanges, such as Crypto.com, pool cryptocurrency deposits, and use it to offer interest-bearing loans. In exchange for depositing their crypto with the lender, some of these interest payments are funnelled to savers. The exact rate you could earn varies depending on the coin and term length you choose.

Through Trading:

Bitcoin trading involves buying and selling Bitcoin via an exchange platform with the goal of earning profit, which may or may not be invested in additional crypto holdings

Claiming Airdrops:

‘Airdrops’ are a marketing strategy used by certain crypto and blockchain companies to incentivise awareness raising and attract new users or investors.

Help To Find Bugs:

Certain crypto developers may offer incentives to users who help them find bugs or glitches in their systems.

Incentivised Learning:

A few trading platforms allow users to earn small amounts of cryptocurrencies by completing lessons on crypto and blockchain-related topics.
