Each coin comes out in different ways, but usually I expect to see growth of at least 15 %. In General,I prefer long-term investments, they attract me much more.
I prefer to allocate my investment to a few coins, so I have a lot of altcoins. This is quite safe, because if something happens to one of the coins, my losses will be minimal.
I think Ethereum is a very promising coin, but do not invest all your money in it. And it's not because it's bad,it's just quite risky to have an investment in just one coin.
I don't know what coins you have, but if you think they have a good perspective, then I would recommend you hold that coin. It is possible that it will be much more profitable.
Perhaps you are new and do not know that such price jumps in the market - normal. This allows the price of cryptocurrency to rise. You just have to wait out this bad period.
Now the market is in a very sad state, as the fall in prices lasts for a long time. But I think that in the near future everything will begin to grow, albeit slowly.
