Don't worry, this friend is just a bad bitcoin and altcoin trip, we have a long future so we are sure that in the future we can feel that kipto money will rise again as before and become the most expensive coin.
Crypto have a great future. This down trend will end and everyone has going to enjoy the fruitful results for sure. Crypto help t have extra income which used for services. I do not see that it will end soon because it just becoming more popular. Now that it is legalized in some countries and try to adapt in some businesses, there is nothing to worry because technology change and transactions have to make more easier.
