Did you just import the address without sweeping or did you send your Bitcoins to a new BitGo address? I have never heard of BitGo, but it sounds like one of these web-wallets that don't allow you to access your keys (seed). In case of that, it's not possible to claim your Bitcoin Cash yourself.

Edit: Did you have your Bitcoins in your Bitgo wallet on the moment the fork?

What does you, owning 99 Bitcoin addresses have to do with the top 100 richest Bitcoin addresses?

Satoshi Nakamoto has not stored all his Bitcoins on just one address, he has them spread out over multiple addresses with each 50 BTC.

Litecoin is a good alternative for Bitcoin till the lighting network is released, it basically works the same but the fees and confirmation times are reasonable. I prefer to use Litecoin over Bitcoin when both are accepted, just because micro-payments are possible using Litecoin. But Litecoin is not the answer to the problems Bitcoin has, as in technology. If they would substitute Bitcoin and therefore get the same traffic then it would also struggle with scalability problems.

Bitcoin Diamond forked at block 495866, you can add this one to your list. But I'm not sure if the network is already open for public.

There is one big difference, with an offline wallet you can't send transactions to the miners. With an online wallet this is possible, you can view the blockchain and send a signed transaction to the miners, they will add it to the blockchain. But some offline wallets allow you to sign transactions being offline, then you can send that transaction with an online wallet or a webpage to the miners. So you're basically doing the whole process then on you're offline wallet.

Some people think gold is better because it's actually used in products, like jewelry. But for a payment method like Bitcoin is, it isn't better at all. If you would use gold as a means of payment you would have to weigh and break it to the right mass to actually pay exact amounts directly, without converting. You don't have to convert your Bitcoin to fiat to pay for goods or services, as many suppliers accept Bitcoin.

One thread it enough, you don't have to post the exact same thread six times. But do I understand it correctly that you sent your Bitcoins to the wrong address? Then you should just hope that a miner doesn't add your transaction to a block. The mempool should dismiss your transaction after about 72 hours, which means you get your Bitcoins back in your wallet.

You described the best the technique for buying and holding your cryptocurrencies. I try to this technique every time I invest in crypto, but sometimes I'm just a little too lazy to move small amounts of coins out of my exchange account. Luckily I never lost anything because of that.

That what all altcoins say, but I've never seen something that could really dominate Bitcoin based on it's technology. Some altcoin like Monero have something functional to add but I don't think that it could really substitute Bitcoin, as it still has the biggest community, age and trust.

I'm not really a fan of wallets that support multiple coins, most of the time these are wallets that are either cloud or don't support open-source. You better just get two separate wallets for these coins. For Litecoin I can recommend Electrum LTC or if you want to run a full node Litecoin Core. To answer your second question, LTC mining is not profitable using GPUs, as the mining is quite dominated by the ASICs

Looking at your profile I can see you have been around here for quite some time, so I guess you're familiair with Bitcoin? Then Litecoin is the perfect altcoin for you, it's quite identical to Bitcoin but not overpopulated. Sending them works exactly the same as Bitcoin, only difference is the the address prefix you're sending your coins to. Litecoin's transactions time are very fast, never got any problems like Bitcoin does and the fees are negligible.
 

Why would you give the responsibility of your coins to some random people while you could easily do it yourself? If you really own a significant amount of Bitcoin, then you could easily store them on some old laptop or an android phone.

Bitcoin is in my opinion much more valuable than Ethereum, as it got a bigger community and also has much more age than Ethereum. The Bitcoin Core open source project has the best developers in the world, they have been running Bitcoin smoothly for over 8 years. Although there are problems right now, they have been working already on a fix.

If you only lost your copy but you're still able to manage your Bitcoin, then it's not really a problem. Because you still have the ability to make either a transaction to a different wallet of yours or export the private key again. But if you're copy is lost and it is not included in the wallet then your funds are gone forever. So make sure you don't lose them.

Isn't blockchain.info capable of this too? But to answer your main question, I don't recommend storing high amounts of Bitcoin on a web-wallet, especially not when you're going to store them on your phone. You would be much safer if you just installed a desktop wallet, preferably offline. Armory, Electrum and Core are good choices.

That's a bad idea if you want you'rre transaction to be picked up by miners. The average fee at the moment ia very high so if you would send a fee of 0.0001 BTC your transaction would stay in the mempool till they release it, because miners can profit more from users that send higher fees.

Het probleem ligt of bij Coinbase of bij Litebit, ik vermoed Litebit. Heb je toevallig het transactie id? Dan zou je kunnen kijken of de transactie al bevestigd is en het probleem dus bij Litebit ligt.

Heb je de reactie van brobbel überhaupt gelezen? Hij verteld namelijk dan een herstart geen zin heeft. Jouw transactie zit hoogstwaarschijnlijk vast in de mempool, dit is een verzameling van alle transactie die nog bevestigd moeten worden. Doordat jouw ingestelde fee onder het gemiddelde zit, wordt deze niet opgenomen door de miners om mee te nemen in een volgend blok. Je zal dus moeten wachten totdat jouw transactie automatisch uit de mempool wordt gegooid en dus weer in jouw Multibit wallet beland, hou er rekening mee dat dit enige dagen kan duren. Er is ook nog kans dat jouw transactie wel wordt opgenomen, omdat het toevallig rustig is zoals brobbel al zei.

Armory is way more secure if you know how to use it, it's less user-friendly than Electrum. It has SegWit implemented, allows you to manage your keys and does support sweeping. For android, I assume you use it as a portable device, you don't need to have an advanced wallet like Armory, just use it to store small amounts of Bitcoin for doing micro transactions. Every web-wallet that allows you to see your private would be fine for that.
