I don't think it will be necessary trying to convince anyone to invest in bitcoin because I believe bitcoin has passed this stage, especially those that are sceptical about bitcoin . Bitcoin has proven to be among the best assets, if not one of the most sought assets. Therefore I believe it is only the blind that needs someone to convince them before they will see the potentials of bitcoin and decide to start buying. Who ever that is still skeptical about the potentials of bitcoin at this stage that bitcoin has gotten to doesn't need any form of convincing, they will continue as a no coiner and before they will realise there mistake of not buying bitcoin, it would have been late.
You are absolutely right, because it is very difficult to invite or remind people who really refuse to be invited, especially in terms of bitcoin investment. So the point is we don't need to bother with this, because whether other people invest in bitcoin or not, I don't think we will gain or lose. So with that, then we better focus on the bitcoin investment that we are running. Because in my opinion, even people who are currently skeptical of bitcoin, without the need for us to invite them in the future, I am sure they will definitely be tempted to invest in bitcoin. Then about late or not, I can't say that people who are aware of the potential of bitcoin in the next 5 years are too late to invest in bitcoin. Because in my opinion 5 years from now if someone starts to invest in bitcoin, it might still be good. Because bitcoin is a very potential asset and continues to grow, so the point is not to be discouraged for people who may feel it is too late to invest in bitcoin. Because in my opinion people who can be said to be late to invest in bitcoin are people who are not aware and refuse to invest in bitcoin.
