Hey guys so I'm new in this forum and wanted some advice. I've been doing some research about cryptocurrencies and the block chain tech.  I'm interested as hell. I missed out the first opportunities of investing back in 2010.  I know its still not to late to invest or is it ?

Also my strategy was going to be simple buy the ledger nano s and buy in about $200 to get started and each month invest about $100 and keep doing that and just holding it for at least 3-4 years and see what its worth by that time as I believe the value of bitcoin will go up aswell as other currencies. 

Any advice would be much appreciated also what would be a good exchange to use with minima fees ?
