BlockFi and Celsius Network are two platforms that allow you to earn interest by providing liquidity.
✅ 𝔹𝕝𝕠𝕔𝕜𝔽𝕚 is a crypto bank born in New York in 2017. In 2018 the startup raised over 4 million dollars thanks to Fidelity, from investors such as Akuna Capital, CMT Digital, Recruit Strategic Partners, Galaxy Digital Ventures, Morgan Creek Digita and Devonshire Investors .

BLOCKFI (BIA)
BTC = 6%
ETH = 4.5%
Litecoin = 5%
USDC = 8.6%
GUSD = 8.6%
PAX = 8.6%

The platform also allows the purchase in USD currency of the USDC, GUSD and PAX stablecoins, which can then be exchanged within the app in BTC, ETH, etc.
As mentioned, keeping Bitcoin, Ether, Litecoin, USDC and GUSD on the platform earns compound interest, paid in BTC, ETH, LTC, USDC and GUSD, every month.
To raise the level of security of token storage, BlockFi uses the famous American exchange Gemini as its main wallet (other investors are Galaxy Digital, Susquehanna and Coinbase).
Deposited money can be withdrawn whenever you want, interest is updated day after day and paid once a month.

How do you deposit? Just press on "deposit" and choose the crypto. To transfer them out on "withdraw".
The platform also allows you to obtain loans by giving cryptocurrencies as collateral, in order to obtain liquidity without having to sell them. Loans can be obtained up to half the USD value of the cryptocurrencies left as collateral (disbursed by bank transfer or stablecoin). Just go to "New Loan".
The "Trade" function allows the exchange between the cryptocurrencies while the price of the cryptocurrencies that you want to exchange for 1 minute is blocked.

🅱🅾🅽🆄🆂 🅲🅷🅰🅿🆃🅴🆁: until August 14 by depositing at least $ 500 in crypto you get a bonus of $ 20 (just keep them locked until September 14, 2020). The bonus is credited directly to your balance. For sign up: BlockFi (Sign Up)

✅ ℂ𝕖𝕝𝕤𝕚𝕦𝕤 ℕ𝕖𝕥𝕨𝕠𝕣𝕜 works the same way, only that unlike BlockFi you have to download the app so it is only available for mobile devices. The funds deposited are guaranteed by an insurance company whose provider is BitGo. It is based on the Lloyd’s insurance company and behind it sees investors including Morgan Chase. The maximum insured countervalue is USD 100 million (in the case of hacks, black swans or problems attributable to the platform leading to the loss of user funds).

BTC = 4.56%
Ether = 4.56%
Celsius also supports Bitcoin Cash, Bitcoin SV, Dash, Litecoin, Stellar, OmiseGo, Gemini Dollar, etc

Here the interest accrued for BTC is a bit lower but more crypto is supported. Interest can also be received in Celsius Token. The "barrow" feature affects USD and stablecoin. Through "CelPay" you can send crypto to other members of the Celsius Network or share a link on your favorite apps.

🅱🅾🅽🆄🆂 🅲🅷🅰🅿🆃🅴🆁: it is certainly very interesting because it is possible to take advantage of bonus continuously. There is a bonus for signing up to 20 dollars in Bitcoin (you must deposit at least 200 dollars and keep them blocked for at least a month) which you can take advantage of using a refer link: Celsius Network (Sign Up)
Or by entering the code manually: 136530859e

However, the app always adds new bonus (in the past it has come to give up to $ 100 in bonus by entering multiple codes).
Each code entered guarantees a bonus, the important thing is that you respect the deposit conditions and keep the crypto locked until expiration.
Insert the referral code (first 20 dollars bonus), after a few days you can enter the Promo Code obtaining another 20 dollars.
Just go to: Profile / Enter A Promo Code and write SUMMER

In the following months check new promotions because the Promo codes are updated continuously.

⚠️WHAT IS BETTER?
I personally use both platforms. About 50% of BTC and Ether are deposited on BlockFi.
About 30% of Celsius. Obviously, non-custodial wallets are always preferable to centralized platforms, however these two wallets are really safe and well insured. In addition, the interest rates provided are very high.
