It probably isn't all that wise to seek investment advice off those that are going to be biased to Bitcoin. Basically, as you can see most of us will suggest that you keep it in Bitcoin, after all Bitcoin has shown throughout its short history that it has kept going up, and hitting new highs.
Although, I'll recommend something different; if you are seeking financial advice then seek a professional, and not someone on this forum. Though, I think largely these types of professionals are blagging it, so choosing one might be difficult.
So, do your own research. Look at what could effect Bitcoin in the short term, what could effect it in the long term, and decide whether it would be best to keep that 1 Bitcoin, and let it potentially appreciate in value, or use it to invest in something else. No one can tell you what to invest it in, since it's your money. However, even if you wanted to invest it into something else, you could probably only invest it into something which has the potential to give you less money over time.
At the moment, Bitcoin is a exciting technology, and with that comes a certain hype, plus because a few of us actually think it's revolutionary it has the small chance of becoming a mainstream currency. If that were to happen it's likely that Bitcoin would see a exponential value increase. Also, Bitcoin has probably been the most profitable investment in the last ten years, and it hasn't shown any indications of it slowing down. Though, that's not to say that it won't slow down or even completely stop being profitable.
Okay, so I've given you conflicting views there, but my opinion is; there are certain things that Bitcoin has to overcome for it to become a mainstream currency, I use the phrase "small chance" because I believe currently there is a small chance because it has certain problems it needs to overcome. Once of the major ones I think is; complexity for the general public, which has improved significantly since its creation, but it still has a long way to go before mass adoption. Luckily, even if it wasn't to become a mainstream currency, there is still indications that it'll be profitable. Basically, Bitcoin allows you to manage your own money, therefore you control it. In the modern world, this is rare, most people need to use banks, because that's how they get paid, and that's what their loan companies or landlords require. Therefore, they are almost forced into using a third party to manage their money. On top of this; you are then introducing inflation, because there is no cap on the amount the government can inject into circulation. Bitcoin on the other hand is somewhat deflationary by design, therefore the longer it is in use, and popular the more likely it's to appreciate in value. This is what we've seen consistency over the years, and if you were to compare Bitcoin to any other investment, I would bet you'd come to the conclusion that Bitcoin would have been the investment with the highest return.
Despite this, there's no guarantees in life, and ultimately it's down to you, and your personal judgement on what, and how to handle your money. However, this is something that is ingrained into every person who uses Bitcoin, since it's the only currency which realistically allows you to do so.
Big Thanks for the much insight, grabbed a whole lot.
Despite all of this my idea is best and getting a professional for more insight.
Thank you....You will be grand
