Don't store your money for investing if you afraid to lose, investment is high risk to store your money. Even you store them into cryptocurrency which is known have a high volatile price you will not comfortable on it. Choose bank account to store your money but you will not get anything although you store them in a few years. I guess, something that must be known by some people when they start to invest is they are willing to lose their money, that is the  main risk in investment place.

All investors/new comers need a knowledge when they start to invest, most of them who leave in lose situation are they who didn't know the knowledge of investment itself. So, I'll answer your question based on my knowledge, I won't leave my investment in cryptocurrency although my money has been reducing for almost a half. I'll stay until the price altcoins that I choose goes up again and I'll sell them when I got profit. That is my strategy to store my money into cryptocurrency.
