Buy for what? just want to keep it for a year then resell it? Crypto fluctuates every day, too bad if you don't use it.

I'd only recommend Bitcoin as the safest crypto in terms of price rather than altcoin (please explore the history of bitcoin prices in late 2018 to mid 2019). If you have a mining option, that means you have time to do it. But I don't want to advise you to mine, but rather to active trading instead. With an expectation of 10% -15% profit, you might get it in just a week or a month if you have a good price analysis.

I emphasize here, this is not a return. This is a way of trading that has a 50:50 chance between profit and loss.
