1. Unemployed people do not have income so they do not dare to invest in Cryptocurrency.
They are being given stimulus packages via airdrops and it is being said that some of them are in a hurry to invest into crypto.
2. The psychology of fear that if we die by Virus and die, investing in Cryptocurrency will not bring anything when we die
Who says that cryptocurrencies won't bring you anything if you die by virus? It may buy you some place where you intentionally want to get buried, it may also bring some peace and smiles on your family members' faces because you've invested some of your money into crypto and leave that crypto to someone close to you by letting them know about the same. As well, allowing them to sell it whenever they want to, so they can hodl and then sell it at better prices.
3. In a difficult economy, investors need to withdraw assets and sell cash to maintain businesses such as payroll, purchase and sale of goods instead of investing in cryptocurrencies.
I agree to this one, that they need money in order to pay for things but cash? I don't think so because cash is also paper money and everyone is being advised to use digital payments mostly, so to stop the spread of virus via cash. Don't you think this is an opportunity for digital cryptocurrencies too?
4. The disease has not yet been controlled, the economy has not shown signs of recovery, so investors are afraid of not participating in the Cryptocurrency market.
No, the total crypto marketcap is worth nothing compared to trillions of $$$ worth of markets you're speaking about. So, investors may not be taking a chance now due to halving but may prove us wrong that BTC will remain in sideways, by just liquidating all the shorts till a level that even these shorts won't have thought of.
