That's why if you wanted to be a holder, you need to have a lot of mental toughness. What I mean is that you should not just look at the everyday price because you might be thinking that you are not making money because of the worsening market conditions.
But as traders, you really have a chance to gain profit, but you need to have the expertise and the knowledge, otherwise you might lose in the beginning and became to question yourself and then you felt you are just wasting money and time and easily will get burned and quit.
hodling is really really difficult specially of you do not have an influx of cash on a weekly/monthly basis. but of course there are always alternative altcoins which you can study and give focus to hodl like the ilcoin. take a look and you'll be amaze of its non stop development.
And that will give you an option to sell.
Anyway, that would be a life in here. Nothing has to keep holding and even you have a lot of back-up resources still, there is a time that we need to sell them off. Gaining is what we look for and not keeping it just like a treasure. But for this hard time, I'd rather hold for a while and wait for the market to recover. Yes, it probably a long wait but it might be in need unless if you want just to lose your money.
I don't see how altcoins could be able to sustain the market dumps and never it looks profitable than of Bitcoin. Having them an option, I'd never think it works.
