Its not possible for you to make an investment and not consider the risk associated to it, but if you're investing on Bitcoin in particular, then you're safe and have reduced the chances on the risk, cryptocurrencies in general is a game of those who are ready to learn and go by the way of expectations in choosing and doing the right thing, if we so wish, we could achieve more in it than making losses.
Everyone certainly does not want to experience losses so they will continue to try to get profit through good ways such as trying to choose the best assets among the many cryptocurrencies today. And Bitcoin is the right choice that has been tested for years so that it can be quite suitable as an investment option for many people even though the level of risk is very different from the others. Because it is true as you said that in any case, of course everyone must understand the risks first before making a decision.
Still investing in anything has a risk and so is the bitcoin
BTC, however, the risk reduces considerably if you invest in the bitcoin only,
I do not say the same with other cryptocurrencies but when you have the major portion of your portfolio in bitcoin, you can consider yourself save and in the long term you should not be worrying about the ROI.
Yes, in the short term, there may be times when we are in the overall loss but if someone is following the DCA strategy, he won't be in a negative.
A perfect example here is of
Michael J. Saylor who is the CEO of MicroStrategy. He is the bitcoin millionaire and he always buy bitcoins when the bitcoins falls to support at certain levels.
