Safest risky investments? What the hell are you speaking about? I fully disagree with you - Bitcoin is the less risky investment for me as it's #1 cryptocurrency and it will rise again for sure. What concerns other coins, I'm not sure that they won't disappear the next day as most of them don't improve anyhow.
It seems you don't understand what I said above, because in general I also don't say it's bad for Bitcoin and Bitcoin investment because I've known Bitcoin for a long time and still want to keep it until a new high price occurs in Bitcoin.
And I'm also not asking you to agree with what I'm saying because I'm just saying that the level of risk in every investment is always there even if the investment is in Bitcoin. So I think there is nothing wrong here because I also like investing in Bitcoin not investing in anything else. I hope you can understand what I mean by this OP.
