Not reliability of investing in the digital assets like bitcoin and if you are not contended with your holding, hodling gives you the opportunity to the peak you desires.
There is no better asset to diversify to, bitcoin should be the first choice and the second choice except you have some real-life assets that have potential value to appreciate as time goes on then you can alternate it with your investment is bitcoin. The market is full of worthless coins, it will be a total error to think that you can get smarter by diversifying into any shitcoins because you will lose in the end and regret why you made such a costly mistake.
