I guess that I can excuse their lack of proper knowledge.about the best option for crypto investment
Don't you think you will still get them more confused by using the word Crypto as a newbie they might go astray by investing into the wrong coin thinking it is Bitcoin it could have been proper you say Bitcoin investment rather than crypto investment.
And I dont think it is much necessary to get all proper knowledge about the best option for Bitcoin investment before investing into Bitcoin and I don't think there is any best option as your options might not be some else options every investor has option that works for them.
Some people succeed in there Bitcoin investment and some didn't and those that didn't succeed there are people inside that failed because of wrong approach.
As long as bitcoin investment is concerned, there is no wrong strategy for accumulating bitcoin for long-term profit. Even though you use the lump sum strategy, the DCA strategy, and buying the dip strategy, you will not fail in your bitcoin investment. The main reason why we always advise newbies to make use of the DCA strategy is that not every investor has enough money to lump sum, and buying the dip strategy will delay newbies accumulation journey because they are not certain if a dip will happen today or tomorrow, but with the DCA strategy they are open to consistently accumulate bitcoin either on a monthly or weekly basis even if bitcoin is increasing or decreasing, which will be more effective to them than buying the dip. The thing that can make you fail in your bitcoin investment is when you invest all your money in bitcoin and fail to make provisions for your emergency funds with the idea of getting rich soon.
