You should read about what requirements that Bitcoin wallet needs.
Requirements,
-High-end PC (Intel i7, 64-bit (Windows 7 with full updates), 16GB RAM or more)
-170GB+! You should ready your HDD (SSD recommended) capacity for that big amount of files (Blocks)
-Internet speed more than 50Mbps
-Internet Router setup (UPNP must be on, no firewall filters, no IP filters) for sync on peers
-Anti-virus, you should exclude Bitcoin on scan monitoring
-Encrypt your wallet, don't put any of your informations when making a passwords, some hackers lurking your identity, bitcoin address, etc.
-You should backup "wallet.dat" to your cold storage (USB, Memory card, Disc (Not recommended if not proper used))
-PC Maintenance (CCleaner, etc...)
When you leave your PC/Laptop opened with bitcoin opened, you should monitor it using TeamViewer (Remote PC by using Smartphones).
These specs could be the optimal specs if you want to run an unpruned version of bitcoin core (bitcoin-qt) smoothly (haven't checked tough, but i seems plausible to me), while having hundreds of unspent outputs and addresses and do dozens of transactions daily.
If you run bitcoin core with a pruned database, the HDD space will be reduced dramatically, and if you don't mind the fact that core might stall for a couple of seconds once in a while, i'm pretty sure the other specs can be a bit lower to...
A different sollution is to use a HD SPV wallet like electrum. I don't know the minimum specs, but i've ran electrum on a 10+ year old laptop without any problems... It uses just a couple of Mb diskspace and runs smootly on windows, linux, mac or andoid...
I'm also a bit confused about the fact that somebody recommands to monitor your pc using teamviewer from your smartphone. It's the first time i hear about this...
