I kept BTC and ETH under my pillow

Do you still have faith in digital currency?
Without a trusted cryptocurrency exchange (after exchangers collapsed one after another), it'll be difficult to regain confidence/faith in digital currency. The analogy will be like if retail investors have lost confidence in the bank or currency exchanger, money will be worthless. Where and how do we keep stablecoin and trade in cryptocurrency?

Regulated vs Decentralized
Someone suggested crypto should be regulated and investors should be protected with SIPC like stocks. But this is against the reason cryptocurrency is developed - decentralized.

Investipedia:
"A cryptocurrency is a form of digital asset based on a network that is distributed across a large number of computers. This decentralized structure allows them to exist outside the control of governments and central authorities."

Blockchain Technology
Cryptocurrency may be dead but not blockchain technology. The problem is not digital currency but greed. Some invest beyond their mean and YOLO all their hard earn money without knowing their risk. And when there's greed, scams are everywhere. With human creativity, Blockchain tech will evolve into something useful - glim of hope in NFT.

Digital currency Insurance
Digital currency is still at its infant stage if you compared to stocks. BTC mining first started in 2009 and trading gained popularity in 2017 when it was only USD 1k (peak at USD 69k, current price USD 24k). Cryptocurrency exchangers collapsed and algorithm stablecoin (Terra stablecoin) crash will not be the last crisis, more will come. If investors are not protected, there'll be no faith. But there's still hope. If bank or hedge funds can provide some form of insurance when trading digital currency, confidence can be restored.

Sadly I'm keeping my BTC and ETH under my pillow (cold wallet or ledger) for now.
