The main differences between crypto spot trading (trading the actual cryptocurrency) and crypto CFD trading (trading on the price movements) are:

‍Ownership: With spot trading, you own the underlying cryptocurrency and have to store it in a crypto wallet or exchange wallet. In CFD trading, traders can speculate on the price movements of cryptocurrencies without owning the underlying assets. Note that exchange wallets are controlled by cryptocurrency exchanges, which means they control the private keys assosiated to your exchange wallet. If the exchange is hacked or goes bankrupt, you could lose access to your crypto assets. This is why many traders will transfer crypto to their private wallets. CFDs do not have this risk.
‍Leverage: CFDs allow you to trade with leverage, controlling a larger position with less capital. Cryptocurrency spot trading is usually on a 1:1 basis, although you can also have margin accounts for spot trading.
‍Short selling: It is possible to short sell when you trade cryptocurrency CFDs, but not in crypto spot trading.
‍Costs: Cryptocurrency spot trading involves commission. Crypto CFD trading has no commissions but instead will have a spread cost and usually come with daily financial charges (except on swap-free accounts).

Cryptocurrency prices can be influenced by various factors, including:

Market demand and supply dynamics
Regulatory developments and government policies
Technological advancements and upgrades
Adoption and acceptance by businesses and individuals
Security and hacking incidents
Investor sentiment and market speculation
Macroeconomic factors and global events
Media coverage and public perception of cryptocurrencies

Before making trading decisions on cryptocurrencies, you can perform research and analysis using the following methods:

‍Cryptocurrency fundamental analysis: Evaluate the project's whitepaper, team members, partnerships, technology, use case, and community support. Analyze the project's potential for adoption and its competitive advantages.
‍Cryptocurrency technical analysis: Study price charts, indicators, and patterns to identify trends, support and resistance levels, and potential entry and exit points. Use tools such as moving averages, RSI (Relative Strength Index), and MACD (Moving Average Convergence Divergence).
‍Crypto market sentiment analysis: Monitor social media platforms, online forums, and news sentiment to gauge the overall market sentiment towards a particular cryptocurrency.
‍Risk management in cryptocurrency trading: Consider factors like market volatility, liquidity, and risk-reward ratios when assessing potential trades. Set appropriate stop loss and take profit levels to manage risk effectively.

‍ It's important to note that investing or trading in cryptocurrencies carries risks, and it's advisable to seek professional advice and understand the risks involved before engaging in cryptocurrency trading.
