Be Among Smart 8%
Only about 8% of bitcoin owners are estimated to keep their coins in complete safety and privacy. There are hundreds of bitcoin wallet apps. Most wallets are custodial, therefore — not secure, not private, and not independent.
Even if a wallet is non-custodial, it may still not be secure. Only reproducible wallets are completely secure. Mycelium is among them. Mycelium is the most popular among them.

Self-custody Made Perfect

Newbies, Pay Attention!
How to make your funds secure?
Make a backup by following the instructions in the app.
What if you lose your phone? 
No problem. It takes one minute to restore your accounts from your backup. 
What if you lose your backup?
You lose your money.
What's the point of putting up with such inconveniences?
Because bitcoins are better than money in a bank. With Mycelium Wallet, you avoid banking nonsense. Payments can not be reverted, suspended, or declined. Accounts can not be blocked. No cross-border control and fees. Storage is secure and free. No subscription fees of any kind. No payment limits; no maximum daily or monthly amounts.
How much do payments cost?
It depends on the situation in the Bitcoin network and how urgent you need to pay. It is you who assigns the miner fee in each case, so be careful. If you offer too much, you spend too much. If you set the fee too low, you delay your payment. The app offers several standard options, but you're the only one who makes the decision.
What is the main drawback?
There is no one to address your complains to. Mycelium does not touch your money. It is only a relay between you and the Bitcoin network. There can be no fundamental Bitcoin failures, but things can slow down, and your wallet may be out of sync for a while. On the other hand, custodial wallets (those that explicitly stand between you and your money) do not solve the problem entirely anyway. But you still pay for an illusion of smoothness with the full physical control of your funds given out to some random people.
One more piece of advice: NEVER store your bitcoins on the exchanges.
If you use centralized exchanges to buy bitcoins, withdraw your assets as soon as you bought them. You do not control your coins there. Bitcoins are like physical coins. That's why crypto-exchanges are vulnerable to outright robbery. And that is YOUR problem. The relevant regulation is inadequate. In case of a hack, no reimbursement of funds is guaranteed to you. Take a look at the comprehensive historical list of cryptocurrency exchange hacks here.
