When advising someone concerning a good digital currency for investment it's best to advice the person to focus on the one that's more decentralized, Bitcoin is the best amongst all that suits that description, no other ones come close to it, even though some people do feel their are good alternatives for investment but none have been more secured like Bitcoin.
Anyways Bitcoin investment is not for everyone it's for those who have hope in it and believe that If they can remain calm and patient while accumulating it continuesly they'll get better reward in the future, although some people still choose to risk on other coins asides Bitcoin but the best coin for investment is Bitcoin and no other.
You should never advise anyone to invest. Because if you tell your friend to invest in Bitcoin and if he invests in Bitcoin and after a few days the price of Bitcoin decreases, then he will get very scared and then that person may sell his holding. Then he will put the entire blame for this loss on you. Because you gave him advice.
This is exactly what happened to one of my friends: A friend of mine invested in Bitcoin. He told a friend in his office about his investment, will you do it? He asked his friend to invest directly without saying anything about the risk etc. A few days after investing, suddenly there was a fall in the market and when the new person saw that his investment was losing money, he sold his entire investment. The entire amount of money he had lost was completely blamed on my friend and he had to pay full compensation. So you should never advise anyone to invest. If a person comes to you to learn something about investing, you can tell him the basic knowledge about Bitcoin and show him some videos and say, "This will be useful for you."
There is nothing bad in it if you advise a brother to invest in bitcoin it is now their own choice to accept or not.
Before any advise you might told them how bitcoin investment works the nature of the market, the up and down of the price so they will not panic when such thing occur, that it is also a long term investment and when investing to invest using their discretionary income which is money they can afford to loss, they may not happy with you if you start benefiting from your bitcoin investment for not letting them know before now it is of a true that no time is late to start buying bitcoin but it will be better to be done now.
I think when it comes to investing, it's best to avoid encouraging or disclosing information, and the same applies to investing in Bitcoin. Being too aggressive in telling and persuading someone to invest in Bitcoin can backfire, which can be very dangerous. Because people who don't understand investing certainly don't understand the concept of investing.
Most laypeople simply think about how to get results without considering the process, and that's the danger. When told about price cycles and their potential, laypeople often don't immediately believe it. So, when they're invited to invest in Bitcoin and then there's a price correction, they'll panic. Therefore, in cases like this, it's best to avoid talking too much about Bitcoin investment to laypeople, unless they themselves ask for information.
In that case, I don't think there's anything wrong with informing them, but with the proviso that we don't offer advice that could be considered an invitation to invest. Because, of course, if we do that, when a bad situation arises, we'll be the ones who suffer the consequences. So we just need to tell them about bitcoin, and let them make the rest of the decision themselves.
There is nothing wrong if i give a brother of mine an information regarding to bitcoin i don't mean anybody i see on the road i started telling them about bitcoin investment it seems may be you do not carefully read my post, if you have forgotten i also made mention of telling them how bitcoin works and the risk involved and about the nature of bitcoin how it price moves up and down and to only invest with their discretionary income it's not that am forcing them to invest into bitcoin it is there choice to accept to start buying bitcoin or not.
