I would say that Bitcoin investment is risky for people who are not experienced with Bitcoin, moreover Bitcoin is the most reliable coin in cryptocurrency. But it is true that every person should be cautious before investing, otherwise it is always good for a person to be cautious as he may face losses at any time. Those who are new to Bitcoin investment should not only acquire knowledge about Bitcoin but also have long term plan in mind as investing is never profitable if it is short term. When an investor invests he must hold which will give him good success in future so investing in bitcoins cannot be profitable in short term so invest for long term. Patience is definitely one of the most important things in investing, the more patience one can achieve in the future, so knowledge and experience and patience are necessary for all investors before investing.
I would like to disagree with you because even those who have basic knowledge about bitcoins are not completely risky in bitcoin investment if they hold their investment for long time. I also didn't come here to invest with complete knowledge but tried to increase my investment experience by buying bitcoins every week with the money I had. Remember that every investment involves risk, be it small or large. When the price of a coin falls in the market, the level of risk for investors increases. Similarly, when the price of the coin increases in the market, the level of success of the investors increases.
By investment risk we may refer to market down or dip season. A dip in the market is a test for investors. Those who are able to patiently hold on to their investments without thinking of selling during the dip season reach the peak of success during the bullish season. Invest with a risk-averse mindset and have the determination to hold on to whatever the market conditions are.
I agree with @AirtelBuzz, to invest in Bitcoin you don't need to have full experience of Bitcoin first, just have general knowledge and basic concept to start investing. By continuing to invest regularly, over time you will get to know knowledge and experience Bitcoin and Crypto all by yourself.
And we should look at the market's deep season as an opportunity and not a risk, the more we invest when the market is deep, the more success we can achieve in the bullish season, because when we can buy at a lower price when we buy, it will give us more profit later. Moreover, a DCA user should be can never look at the market conditions, he only has to buy whatever the market conditions are, only then he can achieve great success.
