I am new in this.
I installed trust wallet my mobile phone. I got recovery phrase
But..i can do it whenever i want transactions. Trust wallet is open all the time.
Practically if i lost phone or someone robbs me he can send all funds away...
Not even asking passwords or anything to slowdown process...
I am worrid about sending there lots of sums. Exchange at least you need e-mail confirmations, when some gets access to your phone.

What would be estemated Coinbase value on the first trading day?

When using margin trading i have noticed that USDT interest rate is quite high 40-100%APY depends on exchange.

But how to get advantage of that high usdt interest rate? Peer to peer lending seems to have more like 10-15% APY, far from exchange APY.
Where i can find Good APY for USDT lending?

I don't get it about PERP Futures
For example BTCPERP funding rate 0.12% (binance)

Reading for binance explanation binance won't take any fee. And if the funding rate is positive LONG pays to the SHORT funding rate. There is said it depends about markets, but as i see all funding rates are positive

So 0.12*3*365days=131,4% like more APY

I can easly go long spot long 1BTC and short 1BTCPERP and collecting funding rate with ridiculously high rate. Where is catch, i do not get it?

What happened to USDT margin?
In binance its impossible to borrow USDT or BUSD.
Interest rates have raised significately

I want to buy bitcoin with margin, but I am not sure which is the best way to do it considering commissions.
Practically there is 2 ways
To buy bitcoin futures or lending USDT and buying BTC
Which is the cheapest way to buy it?
