I find investors using the DCA strategy invest for the long term.
Special Considerations Should Beginners Follow the DCA Method for Bitcoin Investments? What Can Be the Outcome -Future
Yes as a beginner it is %100 save to start investing with bitcoin when you have your discretionary income because without that you cannot begin or proceed with your investment plan because the dca strategy is less stressful for them to start with it allows little by little investment for which involves daily,weekly or even monthly according to the provision of the funds available with you, it helps you stabilize your investment and your personal expenses. DCA strategy gives you that strength to be able to continue investment for a long term in as much as it is your discretionary income your are investing with you will be successful.
What do you mean by 100% safe to invest in bitcoin?
How do you know that?
I would suggest that if a person who is planning to invest in bitcoin knows that he has discretionary funds available to invest in bitcoin, then as long as he does not use leverage, then the most that he might end up losing is 100% of the amount that he had ended up putting into bitcoin.
Therefore, when a person chooses to invest into bitcoin, they should not invest more than they are willing to lose... and so then they can choose from within their discretionary funds how much of that value that they are willing to put into bitcoin as compared with other places that they could put the money, such as to invest in other assets and/or save and/or consume with such money that they had chosen to put into bitcoin.
Accordingly, the investors into bitcoin are choosing the amount that they put in, and hopefully the amount that they choose to put in is an amount that they don't need for expenses and that they would not be wanting to touch for 4-10 years or longer.., including that there is a possibility that their investment could end up going down to zero.
At the same time, bitcoin remains an asymmetric bet to the upside, so even if a person could lose 100%, they could also end up experiencing gains in value that are greater than any other place that they could put their time, energies and value. Allocations into bitcoin have to be weighed, and surely bitcoin is not 100% safe, as Bigjoe33 suggested there are both execution risks and there are risks in the asset itself... so presuming bitcoin to be 100% risk-free comes off as quite a fantastical assertion.
