This is not true, it's either you're mixing up facts or not just sure of what you wrote. When comparing Bitcoin with other coins, it's risk is actually smaller than the rest, I mean it's not just one shitcoin or pump and dump coin that can depreciate into oblivion, if you truly understand the Bitcoin network, you'll understand that it's a coin that actually has a great use case and that will be sustainable for quite a very, very long time.

And as for long term profits, it's definitely Bitcoin that one should be picking over eth or any other crypto for that matter, altcoins are generally short term projects cause many of them can only give ROI for the meantime and once they dump you can forget about the project; but Bitcoin is obviously different, it may not actually give short term profit cause it doesn't just 'pump', but if your patient to stay in the network, long term profit is more or less certain.
