In the fall of 2018, I made the most difficult decision for myself, which was very difficult to make and start to implement. For a long time I could not sell my altcoins falling in price, and when I did this it became much easier for me.
Now I store money in Bitcoin and several high-value altcoins.
When the new growth of altcoins begins, I will probably invest in them again, but only when I see that growth is in full swing.
