Sure saying and i totally agree with that every investors should always have it in mind that they should invest in Bitcoin that can last at least whole cycle or more consistently without having a double mind in the market price because many investors always consider the market price before investing but i want to put it to you that any investors that has the full knowledge on how Bitcoin will never be afraid on how Bitcoin is fluctuating in market but his focus will always be investing consistently.
They may know about BTC, but they wouldn't go into it without examples: some are just afraid it won't work for them, and they fear any dip in their way: however, it's a normal thing with BTC, and eventually, it all pays off tremendously.
It is only those newbies that are up coming, that doesn't have the full knowledge about Bitcoin that will be thinking going to Bitcoin investments will not work for them and also it is only those that have it mind that they will never go for long investment but only based in tradering their Bitcoin within short term will be afraid of losing their money, and there is something i want you to understand that DCA strategy is always there to guide not to lose all your money being invested, so with DCA strategy there is no reason being afraid if going to Bitcoin investments won't work for them or not, your focus should be consistent buying providing you have discretionary income.
