If I have $100,000 sitting on the bank earning 0% and the Fed is targeting 2% inflation, I'm losing 2% a year. Then I decide to lend to ABC company at 5%. I'm risking IT ALL (If ABC goes bk) in order to protect my asset from the Fed. That is a defensible decision
But if I have $100,000 worth of BTC that is already protected against money printing and I'm expecting if to go up 5x and THEN I use it to lend to a company like BlockFI, that is just lunacy. I'm risking it all PLUS the 5x appreciation in order to make a few bucks. That's just crazy
Imo, bitcoin holdings for long term (hodl) is the "safest" way to invest in the crypto space.
Local wallets on a clean Linux machine to hold your private keys. Plan your backups for different scenarios - offsite in case of fire, death for estate planning, authorities breaking down your door and seizing everything (asset forfeiture) everything should be in default "closed" and encrypted with non-backdoored methods (forget Windoze). Some early bitcoin og's have paved the lessons learned on these.
Crypto lending business is very safe, imho. My biggest holding is Celsius Network (which had become an irresponsible portion of my crypto pfolio so I diversified 1/3 of the position to other cryptos, but a lot of it went to a competitor, Nexo). The top players (BlockFi, Celsius, Nexo) use Bitgo which is very secure and insured.
These guys issue over collateralized loans to Institutions (Securities Lending, Prime Brokerage) and to individuals (at minimum 50% LTV). If bitcoin goes down 50% overnight, the borrowers get liquidated before it gets there and there's plenty of liquidity on bitcoin. BlockFi had some liquidations during the March meltdown, but Celsius, did not have a single liquidation (allegedly), the borrowers provided additional collateral quickly. It is my understanding that Celsius is bigger than BlockFi on the crypto Institutional Lending business.
Not financial advice, but personally, if I were to go into "cash" for a portion of the pfolio (I would never go full fiat) for longer than 3 months, I'd park it in stablecoins and deposit most to Celsius and some to BlockFi and Nexo. On stablecoins yields are pretty juicy and worth the risk, imho. Heck, they even have yields on PAX Gold, lower APY but good option if want to diversify some to gold.
