So, are there ways to increase my bag without Trading?
Yes there are many techniques to increase your wealth without trading like buying a coin and then holding it for certain period of time (hodling). There is another technique called DCA dollar cost averaging where you keep buying satoshis for a day, week or month.
https://dcabtc.com/Yes, in the DCA (Dollar Cost Average) method, hodler will undoubtedly gain the most. It is one of the best methods, although many people do not like it because it requires patience. When I first started investing through this DCA method, I also thought it would be challenging to make regular weekly investments, but with time I found that it was very interesting and profitable as well.
