Powering & Programming 900 NeoPixels/WeMos?

Hello everyone,
I am new to this community and Neo Pixels. I bought a quantity of 3 of these @Aliexpress

And this WeMos https://www.amazon.com/gp/product/B01IXBWH9Y/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

And lastly this power supply https://www.amazon.com/gp/product/B005T6TLMI/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I am wanting to set these lights up in my room for a relaxing vibe where I can control it using my phone via WiFi.

However, I have been doing some research on powering these lights are not going to be possible by daisy chaining them. Due to a very high amperage need.

Now, let’s do some math for each strip of NeoPixels, 1 LED strip is 5m long, with 60 LEDs per meter. 1 Strip equals 300 LEDs, (300 LEDS x 60mA if all whites are on / 1,000 = 18amps
What am I left with? 3 strips daisy chained is 54 amps! Plus they need to spit out 5v.

What are some good ideas for the wiring and power methods? Do I need random cables going up on my walls where the LEDs begin or end? Will the data be transferred by daisy chaining the 15 meter LEDs?
