First off, there's no such thing as stupid questions. We all have to start somewhere. Right?
Well. Easy to say, yes that would be the right move. The hard part is, when to buy or when to sell, as it's quite difficult to determine the price low and high points of a coin. Also, patience is a huge role here. It could possibly take months or probably years(though it isn't likely). Lookup the price graph of Siacoin. It's a good example.
My advice to you would be to deposit a small amount of money and play with it for a few days. Just so you get a feel of the cryptomarkets. Then when you think you're ready, then go with a bigger amount. Best of luck.
