Lockdowns will not stop the virus from spreading. It will still spread, although not as fast, and will cause panic and chaos if it takes months to be lifted. If people are not going to be tested for the virus, a lockdown is not of much help. On the other hand, we have the recent 17yo boy from South Korea who's been tested 8 times in a row with negative results and then died; after his death, the DNA resulted in a COVID-19 positive. So now I'm wondering... how useful is testing in reality?
Making someone invest in cryptocurrencies during these times is a possible game-over for them in my opinion. You don't want BTC to fall down once again and remind yourself about the family you tried saving by convincing them to invest in BTC - the family has much less money now thanks to your suggestion. And now if they want to get back their fiat, the process involves the possibility of getting scammed, the commissions and, if these weren't enough, they'll have less value than they started with in the end.
Advertising the forum, on the other hand, is a completely different thing. Let them know they can gather a
lot of knowledge by spending their time on BitcoinTalk during the lockdown. After a while, maybe they'll be part of a signature campaign and will stack up their BTC. 2-in-1.
To be honest, Bitcoin isn't helping me very much during the quarantine but the forum is. It's helping me very much actually. Spending time on here makes time pass way quicker so there's less time to think about the worst.
The trick is, I told the person about the pros and cons , at the same time if the person decides to do that maybe he is able to master the shot term trading.
If he is able to start earning through a campaign or provide his services online through this forum this way he is not using his money but at the same time he is earning something .
The thing is even in times of low you can actually earn , trading for short term gives you small small increment , you can even do that on hourly basis.
Signature Campaigns and the services section is always there if you are too scared to loose money .
