People only invest when they see you making money from bitcoin and most of the people invest in bitcoin from their money which they will need in near future and when price decreases they start panicking and selling their assets in loss and start blaming you for this. I have a friend who invested 3000$ in altcoins now he was telling me that he have total 1200$ with him due to market crash and he is in bad need of money so i recommend people to invest in bitcon with your savings only.
that's why bitcoin is the right choice to invest your money compared to altcoin which is riskier and more volatile. but also what needs to be considered is that before investing someone also needs to allocate their emergency money and only invest money that they are ready to invest, such as cold money that they are not too stressed about if it goes down... and besides that they also need to understand the risk of investing in bitcoin. it is more volatile in the short term, so it is recommended to invest in the long term.
