I have been holding some altcoins since January 2018, But then the market crush hard and I am not able to sell my altcoins because I am in loss with these coins.
Even I invested in more established coins like, Waves,strat,Iota,wabi but overall my portfolio is around 40% down so far.
When I am able to see profit? Holding them for long term is worth my patient?
I suggest you to be patience. We are still at Q1 of 2018 which means there is a lot of time for us. Remember this if we will break another ATH at the middle of this year and this is my speculation. It seems you are new in the crypto space. If you are selling in loss and you will be regretting it later.
