Actually, I do not dare recommend investing in bitcoin or not. I myself am in the same situation as you, still hope someday the price of bitcoin will improve and people will have words.
I think if you follow a bitcoin value chart every year, you already know that the bitcoin's time is every time. I can advise them that they will continue to hold you bitcoin and always updated about value and I promise that you can refund your money capital that you invest.
I can tell them that before investing in bitcoin you have to know and you have to accept how risky it is.
