Dont be afraid to make a wallet , read carefully :
Yes, the problem is in time as more transactions will gather in wallet history ,which cant be cleared, the fee for sending bitcoin will increase and for example to send 10$ in bitcoin to someone you will need to pay a fee equal to 2-3$ but when you send smaller amounts the fee percent could be higher i mean can reach even 70% of the amount sent but this can happen only later when your wallets grows in transactions (short name tx).
But the high fees are also when the blockchain network is heavily loaded with transactions in pending, so it is not recommended to send satoshi when this bad event occurs .
However the default fee can be lowered manually by you from 70% to lets say 50% which means the transaction will not get confirmations in the first 20 minutes but in 60 minutes ,which i use too. So i know sending money to be confirmed in 60 minutes is cheaper than you send to be confirmed in 20 minutes.
People are saying that a wallet to blockchain is useless if you intend to sell the bitcoin for RON or USD and a wallet on an exchange website is more cheaper to send money but having a wallet on an exchange website is more risky because as you may heard there was hackers which attacked exchanges and stole bitcoin.
In other words, a wallet on blockchain.info could be a bit more expensive than the one from an exchange if youre sending sometimes bitcoin to different addresses but it more safer . I've never heard of blockchain.info website to hacked ever .
You can make a wallet at blockchain.info and you can sell your bitcoin directly to a trusted user from clubptc or bitcointalk and/or you can create a wallet on locallbitcoins website and to sell it from there to a trsusted user from that exchange but i don't know if that exchange requires a photo from your ID in order to verify the account but the blockchain.info does not require any ID because is a simple wallet not an exchange website with wallets.
When you create your wallet on blockchain don't forget to write down on your personal notebook all the details such as those 12 words ,secret phrase ,secret answer in case you forgot password. Also write down (on personal agenda) the wallet ID ( example
b232-d23d45-sa12j78-awert4567.. ) + password are required to login and are secret, don't tell them to anyone. In order to not waste time to type all the wallet ID you can copy paste on a notepad file and save it on a usb stick. You wont need to login often to wallet , you can check if you money are sent or received without needed to login as you see my wallet
https://blockchain.info/address/15EMX1WRGW6FPi3UHZqCRJv2WLFHZKDVw2 . But when you have to login just copy paste the wallet id from the notepad file and type your password.
Also you can enable 2FA from google but if you think 2FA from google is to complicated to use, you can download and use this
https://winauth.com/ , i used it as 2FA on paidverts and is working fine. Just test it before on another website to get used to it then you can use it on other serious websites.
Remember in the wallet settings you'll have to choose which kind of notification to login you want : by phone or by email .
You will receive the new bitcoin address such as
1D4frgS45Hh78s23A5f433a11... (14 characters) ,the bitcoin address is not a secret sensitive information, many people use it for donations, but the wallet ID (the red combination) and password and other questions are secret do not tell them to anyone.
you can save the notepad file with the wallet id on your computer too for faster access not only on flash usb stick but it is not recommended to keep important files on a computer connected to internet if you dont have security on it.
Also writing down on personal notebook the wallet id is helpful just in case you lose the flash usb stick.
