Cryptocurrencies also allow people to earn interest off their assets. Through the growth of crypto innovations such as staking and decentralised finance (DeFi), anyone in the world can earn interest, otherwise known as “yield”, by holding and staking certain tokens. No intermediary is needed to complete the transaction.
In 2020 alone, the total value locked up in DeFi projects soared 300 times to roughly $21 billion.
Cryptocurrencies and blockchain technology, paired with the global growth of mobile and indeed internet adoption, are tempering rising financial inequalities.
And it is not inconceivable to imagine that in the coming decades, the world will have a much more democratised and accessible financial system. Financial inclusion could be achieved thanks to cryptocurrencies.
i just want to warn people the fundamental principles of staking in proof of stake coins were not designed with a specific monetary policy in mind. they are necessary for the system to function as it is part of the ecosystem of verifying transactions. such returns are often governed by a central authority (ie. ethereum) or a decentralized one (ie. tezos). interest rates at best combat inflation but were not designed to actually gain value for those using this as an investment vehicle. the potential for a 5% or 10% return for example is based on the underlying assumption that the price holds or even increases. but again, the system is often designed to continually reward those that validate transactions. the system does not care that in 10 years there are too many coins and the price of each coin is decreasing. of course modifications to these staking rewards can be voted upon by the community, but again, the primary purpose is to allow for proper processing and validation of transactions on the network. this triumphs monetary policy.
the high interest rates you see right now is due to the imbalance of staked vs non-staked coins. when more people stake coins, the return on staking declines. again this is to balance the ecosystem between those who are invested in staking and those who actually need to use the coins for transactions.
