What is Cryptocurrency?
Cryptocurrency is a digital or virtual form of currency that uses cryptography for security and operates on decentralized networks based on blockchain technology. Unlike traditional currencies issued by governments (fiat), cryptocurrencies are typically decentralized and resistant to censorship. Bitcoin, created in 2009, was the first cryptocurrency, and thousands of others have been created since, each with unique features and use cases.
Profit/Loss Formula:
Profit = (Sell Price - Buy Price) × Coins - Fees
ROI % = (Profit / Investment) × 100
Profit = (Sell Price - Buy Price) × Coins - Fees
ROI % = (Profit / Investment) × 100

Frequently Asked Questions
How is cryptocurrency price determined?
+
Cryptocurrency prices are determined by supply and demand on exchanges. When more people want to buy a coin than sell it, the price goes up. When more people want to sell than buy, the price goes down. Factors influencing demand include adoption, news, regulations, technological developments, and market sentiment.
Are cryptocurrency profits taxable?
+
In most countries, yes. Cryptocurrency profits are typically subject to capital gains tax. Short-term gains (held less than a year) are usually taxed at higher rates than long-term gains. Keep detailed records of all transactions using our portfolio tracker to simplify tax reporting. Consult a tax professional for specific advice.
What is a crypto trading fee?
+
Trading fees are charges imposed by exchanges when you buy or sell cryptocurrency. They typically range from 0.1% to 1% per transaction. Some exchanges also charge withdrawal fees and network (gas) fees. These fees reduce your overall profit, so factor them into your calculations.
What is market capitalization?
+
Market capitalization (market cap) is the total value of a cryptocurrency. It's calculated by multiplying the current price per coin by the total circulating supply. Market cap helps compare the relative size of different cryptocurrencies and is a better indicator of a coin's dominance than price alone.
Is cryptocurrency a good investment?
+
Cryptocurrency can be a high-risk, high-reward investment. While some investors have made significant profits, prices are highly volatile and can drop dramatically. Never invest more than you can afford to lose, diversify your portfolio, do thorough research, and consider your risk tolerance and investment timeline.
What is a blockchain?
+
A blockchain is a decentralized, distributed digital ledger that records transactions across many computers. Each "block" contains a list of transactions, and blocks are chained together cryptographically. This technology makes cryptocurrency transactions transparent, secure, and resistant to tampering.
How do I calculate crypto ROI?
+
ROI (Return on Investment) is calculated as: ROI % = [(Current Value - Initial Investment) / Initial Investment] × 100. Our calculator automatically computes this for you, including fees and annualized returns for better comparison across different holding periods.
